　　Titanium is a metal chemical element, that chemical symbol is Ti, and its atomic number is 22, which is located in the 4th period in the periodic table of chemical elements, and its atomic weight is 47.90, and belongs to the IVB group.

　　Titanium is the 9th most abundant element in the Earth's crust and the 4th most abundant metal element, and it ranks 22nd on the periodic table and is represented by the symbol "Ti".

　　Titanium is called a rare metal because it exists in the crust and lithosphere in the form of rutile and ilmenite, and is processed and separated into a silver-white transition metal. Titanium is characterized by light weight, high strength, metallic luster and resistance to wet chlorine corrosion.

　　In order to produce titanium metal, the rutile is generally mixed with coke or tar and chlorine gas, and then heat is applied to produce titanium tetrachloride (TiCl 4 ), which is then chemically converted into a "sponge" product, and then finally be melted into an ingot form.

　　Titanium’s metallurgical characteristics makes it the metal of choice for many diverse applications such as aerospace, defense, industrial and chemical processing, medical, naval and marine, sports equipment, consumer products and many others. Titanium was first used in the military aerospace industry. Since titanium's density varies from grade to grade and has strong corrosion and erosion resistance, a ceramic-like oxide film is formed when titanium is exposed to oxygen. If the titanium metal surface is scratched, as long as it is exposed to oxygen, the scratch will "heal" along with the oxide film. This feature is extremely important for aerospace.

　　In addition, due to its biocompatibility, titanium is also widely used in the medical field and is used as medical devices such as hip and knee implants, pacemaker housings, dental implants, and craniofacial bone, which will be plated into the human body.
