Titanium is a metallic element, chemical symbol Ti, atomic number 22, belongs to the periodic table of elements IVB group metal elements. The melting point of titanium is 1660℃, the boiling point is 3287℃, and the density is 4.54g/cm³. Titanium is a gray transition metal, which is characterized by light weight, high strength, and good corrosion resistance. Due to its stable chemical properties, good high temperature resistance, low temperature resistance, strong acid resistance, strong alkali resistance, as well as high strength, low density, known as the “space metal”. The most common compound of titanium is titanium dioxide (commonly known as titanium dioxide), and other compounds include titanium tetrachloride and titanium trichloride. Titanium is one of the most widely distributed and abundant elements in the crust, accounting for 0.16% of the crust mass, ranking ninth. Titanium ores are mainly ilmenite and rutile. The two most prominent advantages of titanium are high specific strength and strong corrosion resistance, which determines that titanium is bound to have broad application prospects in aerospace, weapons and equipment, energy, chemical industry, metallurgy, construction and transportation. Abundant reserves provide a resource base for the wide application of titanium
