Diamonds and pencil lead are close relatives?
Diamond is one of the hardest substances known. It can be used to cut and describe almost all other substances. Of course, it also includes brushed glass. Therefore, in industry, diamond is widely used in sandpaper, drilling, grinding and large-scale integrated circuits and other heat dissipation plates.
These unique properties of diamonds are determined by their molecular structure. Diamonds are glamorous, but they are actually close relatives of the black graphite in your pencil lead: they are all connected by carbon atoms. Therefore, the diamond in your hand is easily oxidized-don't burn it, it will burn. ...
The color of diamonds will be deviated due to chemical impurities. Completely pure diamonds should be transparent and colorless. The reason why diamonds are yellow is mainly because they are mixed with nitrogen atoms.
Structure of graphite
Carbon can be said to be one of the most abundant elements on earth-aren't we carbon-based creatures? Organic chemistry is actually carbon chemistry, and carbon is also the basis of life chemistry. But carbon can only form diamonds at high temperature and pressure hundreds of kilometers from the surface.
How old is the diamond?
Geologists believe that diamonds in almost all commercial diamond deposits on earth are formed in the mantle and spread to the surface through deep volcanic eruption. Diamonds produced by these volcanic eruptions usually exist in kimberlite and scheelite. The formation of natural diamonds requires very high temperature and pressure. Only in the limited mantle area about 150 km below the surface can this condition be met. This is really a flaw in the eyes of jewelers and a priceless treasure in the eyes of geologists.
Diamonds may come from stars?
Although most diamonds come from the mantle deep underground, scientists have found that diamonds may also come from stars in boundless space.
1987, a research group has found that there are tiny diamond particles with a size of only a few nanometers in the "whisper" of meteorites. Some tiny diamond particles are wrapped in tiny bubbles. Analyzing the chemical composition of gas can tell us the origin of these meteorites-some of them are similar to the earth and the sun in chemical composition and should be the remnants of the evolution of the solar system; And some chemical compositions are very different, which indicates that they may come from more distant stars.
Just some time ago, a paper published in the journal Nature-Communication announced a more interesting discovery [6]: In a group of meteorite samples, they found diamond particles with the size of 100 micron-far larger than the previously found nanoparticles. Scientists believe that these particles may have been produced in some "primitive earths" in the early solar system, but during the chaotic collision of various planetary larvae in the solar system's childhood, the planetary matrix where this stone is located was crushed and has been drifting in the space of the solar system ever since. It was not until it fell in a desert in North Africa that it revealed its life experience. The study of this rare "extraterrestrial diamond" will help us understand what the early solar system looked like and what happened.
