Titanium is corrosion-resistant, especially strong and light. According to Los Alamos National Laboratory, it is as strong as steel, but only 45% of its weight. Its strength is twice that of aluminum, but its weight is only 60%.
That is, atomic number (number of protons in the nucleus): 22 atomic symbols (on the periodic table of elements): Ti atomic weight (average mass of atoms): 47.867 density: 4.5g per cubic centimeter at room temperature; Melting point of solid: 3034.4 degrees Fahrenheit (1.668 degrees Celsius); Boiling point: 5948.6 degrees Fahrenheit (3287 degrees Celsius) isotope. Five are the most common stable isotopes: titanium -46, titanium -47, titanium -48, titanium -49 and titanium -50. For an element with super power, titanium has a suitable origin story: it was forged in the depths of supernovae or collapsed stars. In 20 12 years, the study of a dying star supernova 1987A found that a supernova can produce 100 radioactive isotopes of titanium -44 and titanium with earth mass.
According to Chemicool, titanium is the ninth most abundant metal in the earth's crust, but it was not discovered until 179 1. British amateur geologist. William Gregor found some black metallic sand on the river bed. After analyzing it, it was found that it was a mixture of magnetite, a common iron oxide and a new metal. Greg called it Manaka Rock, and he found sand in this parish.
Four years later, a German scientist named Martin Heinrich Klaproth discovered an unprecedented chemical element in a Hungarian ore. He called it titanium, and it was later confirmed that Greg's Mana copper mine also contained titanium.
According to the Royal Chemical Society (RSC), the first person to refine titanium into pure titanium was M.A. Hunter, an employee of General Electric. However, it was not until 1930s that William J. kroll invented a method for extracting titanium on an industrial scale. The so-called Kroll method is to first treat titanium oxide ore with titanium oxide to produce titanium chloride. Next, magnesium or sodium is mixed with titanium chloride in argon (according to RSC, it will be quite explosive to allow oxygen to enter the process considering that titanium has high activity for oxygen). At the temperature of 2 192 degrees Fahrenheit (1200 degrees Celsius), magnesium or sodium reduces titanium chloride to pure titanium. According to RSC, the efficiency of this process is about 10000 times that of ironmaking, which helps to explain why titanium is a more expensive metal.
Titanium is a transition metal, which means that it can use electrons from its multiple shells or energy levels to form bonds. It has the same characteristics as other transition metals including gold, copper and mercury.
Who knows? According to RSC, almost every kind of igneous rock-rock formed by solidification of lava-contains titanium. It is reported that a Boeing 737 Dreamliner is made of 15% titanium. According to NASA, titanium is orbiting the earth: the International Space Station (ISS) has many titanium parts, including pipes. Rosetta project is a research and archiving project aimed at preserving human language and thoughts. It also flew a piece of etched pure titanium outside the International Space Station to observe how it resists radiation and harsh space environment. Earth is not the only place where titanium can be found. In 20 1 1 year, the satellite map of the lunar surface shows the rock groups rich in titanium. These stones usually contain up to 10% titanium, while in earth rocks, it is usually only about 1%. Titanium can be used as raw material for 3D printing. In 20 13, researchers from the Australian federal scientific and industrial research organization 3D printed a pair of light titanium horseshoes for horse racing. This pair of shoes is popular pink. Titanium dioxide "KdSPS" titanium dioxide (TiO2), also known as titanium oxide (IV) or titanium dioxide, is a naturally occurring titanium oxide. A white pigment, titanium dioxide, is used in coatings (such as titanium dioxide or pigment white 6) and is used as a sunscreen because of its ability to refract light and absorb ultraviolet rays. According to the US Geological Survey, 95% of titanium is processed into titanium dioxide pigments. The remaining 5% are chemicals, metals, carbides and coatings. "KDSP" and "KDSP" titanium dioxide are also commonly used in medicine, cosmetics and toothpaste, and are increasingly used as food additives (such as E 17 1) to whiten products or make them look more opaque. Some common foods added with E 17 1 are icing, chewing gum, marshmallows, tonics and so on. KDSP, KDSP, KDSP and KDSP have no restrictions on the use of titanium dioxide in food. However, a new study on mice published in Gastroenterology shows that titanium dioxide particles may have great damage to the intestines of some patients with inflammatory bowel disease. Researchers at KD SPE "KD SPS" of the University of Zurich, Switzerland, found that when the intestinal cells absorb titanium dioxide particles, according to the research press release, the intestinal mucosa of mice with colitis is inflamed and damaged, and inflammatory bowel diseases such as Crohn's disease and ulcerative colitis have been on the rise in western countries for many years. These diseases are characterized by extreme autoimmune reactions to intestinal flora. Some factors play a role in the development of diseases, including genetic and environmental factors, such as lifestyle and nutrition. Now, Swiss researchers have found that titanium dioxide nanoparticles commonly found in toothpaste and many foods can aggravate this inflammatory reaction to a greater extent. This means that these particles can be absorbed from food under certain disease conditions. The researchers of News Report explained that although "KDSP" and "KDSP" have not been confirmed in humans, researchers believe that patients with colitis should avoid taking titanium dioxide particles. A light hard metal commonly used in machinery, tools, sporting goods and jewelry. Jay Narayan, a material scientist at North Carolina State University, said: "The current research shows that titanium dioxide has dazzling functions in the technical field, from solar cell applications to biocompatible sensors." In 20 12 "Titanium Dioxide and Nanometer", narayan and his colleagues reported a method of "adjusting" titanium dioxide, and customized titanium dioxide for specific applications. This material has two crystal structures, called "rutile" and "anatase", each with its own characteristics and functions. Anatase phase titanium dioxide is usually below 932 F (500 C) and transforms into rutile phase at a relatively high temperature. Narayan and his colleagues reported in the June 20 12 issue of Applied Physics Express that they could set the phase of this material as rutile or anatase at room temperature. The bigger leap is that researchers can integrate this titanium dioxide into computer chips. "kdspe" "kdsps" "titanium oxide is also a very good sensor material, so if it is integrated with a computer chip, it will be like a smart sensor.
