Titanium: Element symbol Ti, atomic number 22, atomic weight 47.88, located in the fourth cycle IVB family in the periodic table of the elements. Titanium is one of the most widely distributed and abundant abundances in the earth's crust (6320Ã—10-6). It occupies the ninth place with 0.61% of the weight of the earth's crust. Titanium is second only to iron, aluminum and magnesium. The fourth place is an important raw material for the preparation of titanium slag, synthetic rutile, titanium white, titanium sponge, titanium and titanium materials, and electrode coatings. As titanium metal is silver white, it has a high melting point (1727Â°C), light specific gravity (4.5), high mechanical strength (5), low temperature resistance (almost zero at ultra-low temperature), abrasion resistance, and good ductile titanium (energy) Thin-walled), not easy to oxidation, strong reduction characteristics; titanium oxide - titanium dioxide (titanium dioxide), has a non-toxic, good physical and chemical stability (1000 Â°C after calcination does not melt in any acid and alkali) , high refractive index (2.55 ~ 2.70), and strong whiteness, coloring strength (1150 ~ 1650), hiding power (40 ~ 50g/m2), temperature resistance, anti-powdering and other characteristics, known as "pigment s King". Therefore, titanium and its oxides and alloys are important coatings, new structural materials, and anti-corrosion materials. They are hailed as "the third metal in development after the succession of iron and aluminum," and "strategic metal," and are also "very promising." "Metallic materials" have been widely used in aviation, aerospace, warships, military industry, metallurgy, chemical industry, machinery, electric power, seawater desalination, transportation, light industry, environmental protection, and medical equipment, and have created a huge economy. Benefits and social benefits play an important role in the development of the national economy.
A brief history of titanium ore development
In 1789, the British amateur mineralogist William Gregor discovered a new element (titanium) in the black magnetic sandstone (ilmenite) in the Menagena Valley in the Gonaval region of his parish. It was named "Menaccanite".
In 1795, the German chemist MHKlaproth discovered a new metal oxide during the systematic analysis of rock minerals. It is now that rutile (TiO2) also contains this new element. He took this new element Titans, the son of heaven and earth in Greek mythology, was named Titanium. "Titanium" is what Gregor called "Mena Kinnit".
The geological exploration of titanium resources in China was mainly carried out in the 1950s and 1960s after the founding of New China and was put into development one after another; the deep processing and utilization of titanium resources in China (production of titanium dioxide, electrode coating, titanium sponge, titanium, titanium (Materials, etc.) started with the development of titanium sponge by the Beijing Institute of Nonferrous Metals in 1954. In 1958, Shenyang Non-ferrous Metal Processing Plant was established and a titanium titanium and titanium processing plant was established. The titanium industry system (production of titanium sponges, Titanium processing materials and other products. Until 1997, China's titanium industry has formed two interconnected and complete systems: mine-smelting-processing and scientific research-design-production-application. China is one of the world's exporters of titanium concentrates, wrought titanium, titanium products, titanium oxides and anatase titanium dioxide pigments.
