The main component of the crystal is "silicon dioxide", which is also the most important mineral, occupying more than 65% of the shell components; It also contains various trace metals, so it will cause crystals of different colors; Moreover, crystals are widely associated with various minerals in nature, such as mica, feldspar, calcite, tourmaline, rutile, granite and so on. How are crystals formed? -"The four seas are tumbling, the five continents are shaking, and the wind is coming." Crystals grow in pegmatite deposits and hydrothermal deposits, of course, more in hydrothermal deposits. We know that there is a lot of molten magma in the depths of the earth. When influenced by geological tectonic activities, magma rises and flows into the earth's surface-crust. In this process, due to the changes of temperature and pressure, hot water solution containing silicon dioxide is separated from magma. With the constant change of concentration and composition, the solution is saturated or supersaturated. In a certain structural space (crystal hole) and under suitable thermodynamic conditions, silicon dioxide spontaneously generates crystal buds in solution. Or germinate under certain surrounding rock conditions. Generally speaking, the slower the lava cools and solidifies, the larger the crystal is. Scientific basis and principle of crystal-It has been scientifically proved that rock crystals are piezoelectric, and they can release 8 million seismic waves every second on average, which contains powerful and rich energy. Moreover, the rock crystal has experienced the essence of the earth for more than 10 million years, interacting with the vibration of nature for a long time, and its positive magnetic field hides huge and infinite energy waves. For us who have been exposed to negative magnetic field for a long time, wearing crystal helps to transform our energy frequency into a stronger positive magnetic field and release it, thus affecting our daily life, making friends at work or academic performance. Crystal is a very stable physical and chemical substance. Its piezoelectric characteristics and strong elasticity make its mechanical vibration show excellent frequency characteristics such as high Q value, low mobility, high sensitivity and high stability. Therefore, all oscillators and filters that require high precision and stable frequency must use crystals as oscillation materials. Its uses, such as frequency synthesis, counting, navigation, guidance, fax, computer, communication, timing and so on, are even more important. The main element of Crystal Rock Crystal Shi Ying is silica (timely). We usually call it transparent crystal, but they are the same element. The corresponding chemical composition is silicon dioxide SiO2, which belongs to hexagonal system. Its hardness is Mohs 7, its specific gravity is 2.66, its refractive index is 1.54- 1.55, its birefringence is 0.0009, and it has glass luster (glass has no refractive index). The common response time is mostly huge, but occasionally there are good transparent crystals. All kinds of crystals contain different trace metals, which makes them have their own unique colors. Amethyst contains a little iron, topaz contains a little gold sandstone, and powder crystal contains a little titanium. And SiO2 (silicon dioxide) is generally divided into two types-low temperature response and high temperature response. The growth temperature of crystals is about 550-600℃, and the crystals generated between 550-573℃ belong to low temperature strain. Common crystals belong to this category, and their clusters are hexagonal cylinders (hexagonal crystal system). The agate produced between 573-600°C belongs to high temperature response, and agate is a common high temperature response. Crystal analysis-the frequency at which crystals release 8 million shocks per second on average. In ancient times, people knew that crystals were full of energy, but in the past, science was underdeveloped and it was impossible to study crystals by scientific methods. In the modern two centuries, with the rapid development of science, people gradually discovered the physics of crystals. /kloc-at the end of 0/9th century, scientists discovered that it is piezoelectric. When one end is pressed, the other end will release the charge. In the 1920s, scientists discovered that there was frequency phenomenon in time. The crystal will expand when it is powered on and shrink to its original size when it is powered off. Repeated power supply and power failure, the crystal is constantly expanding and contracting at high speed, but the frequency of oscillation is extremely stable. Due to the high-speed and stable oscillation frequency, crystals are made into chips, which are indispensable raw materials for electrical parts. After years of in-depth study of crystals by many experts and scholars, crystals have been determined to have five functions: focusing refraction, storing data, transmitting information, energy conversion and energy expansion. (1) Focal Refraction In ancient times, people have discovered the focusing function of crystals, and they can also refract light. Through the characteristics of crystals, convex lenses and concave lenses can be made. Powerful and highly parallel, the cutting-edge can be used for eye surgery, and the giant can be used for [Star Wars Project] to destroy incoming missiles and so on. (2) Storage of data When a message passes through the crystal, it will be recorded by the crystal, and the chip in the computer memory has this function. In modern times, the lens and prism of spectrometer have been manufactured. Piezoelectric crystals have different positive and negative charges, which are between 0 and 1 in computer binary. Yes, this is the basis of computers. Today, this memory storage capacity is amazing, and all the data of Encyclopedia Britannica can be input in a volume smaller than an eraser. (3) Transmission of information Many electrical appliances also rely on chips to transmit information, because the frequency of crystal oscillation is stable and the error of transmission marks is very small. Because the oscillation of crystal chip is very accurate and regular, it can be used not only for the time control of electronic watches, but also for the accurate calculation of computers and the transmission of huge information between computers. ④ Energy conversion crystal can convert different energies into other energies, such as light energy, heat energy, acoustic energy, magnetic energy, etc., and can also convert these energies into electric energy. The conversion of solar energy into electric energy depends on the heat collecting chip. Energy can be converted, such as solar collector chip, which can convert light into electricity and electricity into magnetism. Sound, light, electricity, heat and magnetism are all energy sources, which can't be extinguished, but are transformed into different States, and crystal is the best matchmaker. ⑤ Constant-frequency crystal can enhance energy and amplify energy. For example, when a loudspeaker is used, the current is converted into acoustic energy by time (that is, energy conversion), and then the acoustic wave is enhanced (energy amplification), and there will be no sound loss (constant frequency). Electronic signals with the same frequency can be amplified at the same frequency. For example, the crystal on the radio receiving surface will receive the electric waves in the air, and then convert them into sound waves that people hear after amplification. And the multiple between the two is more than ten million times. After introducing the scientific analysis and verification of crystals, let's look at the classification of crystals. There are various classifications of crystals, which can usually be roughly divided into three categories: ① crystal varieties. Usually, we watch clusters of crystals generated by multiple hexagonal crystal columns (hexagonal crystal system), which belong to crystal varieties, such as white crystal, amethyst, topaz, powder crystal, hair crystal and so on. (2) The aphanitic variety (aphanitic variety) has a fragmented appearance, not a hexagonal cluster, but also belongs to a hexagonal system. However, we can't observe their hexagonal crystals with naked eyes, because the crystals are very small, and they can only be seen with the help of a microscope. And this is very smooth in the crystal, because there is "hydrated silica" between the crystals, and agate belongs to this category. (3) special varieties are very different from ordinary crystals, so it is difficult to classify them as obvious crystals or invisible crystals, so they are classified as special types, such as strange and uneven Skelton crystals and phantom crystals with landscape stars. The difference between crystal stone and artificial crystal-crystal stone is all over the world, mostly produced in South America such as Brazil and Uruguay, and also produced in the Qinghai-Tibet Plateau. They grow underground or deep in caves, and the air pressure needs to be about 2 to 3 times that of the ground. In addition, there must be a steady stream of groundwater containing saturated silicon dioxide, and the temperature needs to be between 500-600℃. After tens of thousands or even tens of millions of years, silicon dioxide will form crystals and wait for people. But now that technology is developed, the demand for crystals is increasing day by day. Therefore, we imitate the real growth environment in the factory, mass-produce crystals and cut them into chips to meet industrial purposes. This is artificial crystal, commonly known as crystal cultivation. The growth rate of crystals produced by the factory is quite amazing, reaching 0.8 mm per day. Generally, the 3cm thick quartz for industrial use can be produced in about 38 days, so its value is far less than that of crystal. Artificial lens has low value and fast growth rate. One should be ground into a crystal ball in time, and it can be produced in less than half a year, while the growth time of other crystal chains is even shorter, but it takes tens of millions of years for rock crystals. Rock crystals have absorbed tens of millions of years of energy from nature, which is absolutely incomparable to artificial crystals. We often bring crystals to change our energy and magnetic field. Crystal, recycled crystal and craft crystal-crystals are formed under natural conditions. Regenerated crystals are single crystals, also known as synthetic crystals and piezoelectric crystals. Regenerated crystals are made by hydrothermal crystallization "imitating the growth process of rock crystals". Put natural silica ore and some chemicals into an autoclave and gradually cultivate for 1-3 months (for different crystals). The chemical composition, molecular structure, optical properties, mechanical and electrical properties are completely the same as those of rock crystals, while the regenerated crystals are purer and have better color than rock crystals in birefringence and polarization. After processing (cutting, grinding and polishing), particles of various shapes are crystal clear, dazzling, wear-resistant and corrosion-resistant. Craft crystal, also called imitation crystal, is made of lead glass or rare earth glass, which has no impurities and good transparency.
