Titanium is considered a rare metal because it is scattered in nature and difficult to be extracted. But it is abundant exist in nature, ranks tenth among all elements.
Titanium dioxide is the most common titanium compound, which can be used to make white pigments. Other compounds include titanium tetrachloride (TiCl4) (as catalyst used to make smoke screens or skywriting) and titanium trichloride (TiCl3) (as catalyze for polypropylene production).
Titanium and titanium alloys are widely used in the aviation industry due to the low density, high strength, corrosion resistance, low temperature resistance, non-magnetic, non-toxic, and strong tensile strength. In addition, they are increasingly used in the shipbuilding industry, chemical industry, manufacturing machinery parts, telecommunications equipment, cemented carbide, etc.
With the development of high-end manufacturing, the application of titanium has become more and more extensive. Titanium is a silver-white transition metal with light weight, high strength, high melting point, good wear resistance, good toughness, excellent corrosion resistance, low thermal conductivity, good high and low temperature tolerance, low stress under cold and hot conditions. Titanium and other elements such as iron, aluminum, vanadium or molybdenum form high-strength light alloys that are used in high-tech fields such as aviation, aerospace, and military industry.
With the continuous promotion of titanium to chemical, petroleum, electric power, seawater desalination, construction, agricultural food products, medicine, daily necessities and other industries, titanium metal is increasingly being valued by people and is known as the "third metal", "space metal", "Marine Metal" and "Universal Metal".Because it is an indispensable important strategic material to improve the level of national defense equipment, it is also called "modern metal" and "strategic metal".
It becomes more and more popular in the world.
