[0002] Sponge titanium is sponge-shaped metal titanium produced by metal thermal reduction and is the main raw material for preparing industrial titanium alloy. According to different purities, the sponge titanium is divided into five grades of WHTiO to MHTi4. Sponge titanium production is the basic link of the titanium industry, and it is the raw material of titanium materials, titanium powder and other titanium components. Ilmenite is changed into titanium tetrachloride, then is placed in a sealed stainless steel tank, is filled with argon, and is reacted with magnesium to obtain'sponge titanium'. The porous'sponge titanium' cannot be directly used and needs to be melted into liquid in an electric furnace to be cast into a titanium ingot.
