Sponge titanium is made by oxidation reaction between ilmenite and chlorine gas, which becomes titanium tetrachloride, and then it is put into a sealed stainless steel tank, filled with argon gas and reduced with magnesium metal. ti+2cl 2 = TiCl 4； TiCl4+2Mg=Ti+2MgCl2. Titanium made of sponge titanium, melting point 1660℃, boiling point 3287℃, density 4.54g/cm? .

1. It took 120 years from the discovery of titanium to the first preparation of pure titanium. It took nearly 40 years from the first acquisition of pure titanium in the laboratory to the first industrial production. Many researchers have done a lot of exploration and failed again and again. Finally, DuPont 1948 succeeded in producing tonnage sponge titanium and porous titanium.
Second, Everbright Securities issued a research report on Baoti shares, pointing out that the main reasons for the growth of the company's revenue and net profit attributable to the company in 20 19 were the steady growth of market orders in aviation, aviation and aerospace, the substantial growth of orders in the civilian market, and the growth of production and sales of titanium products.
