Let you know about the raw material of titanium: sponge titanium

Titanium sponge overview
Titanium sponge is a porous form of titanium that is produced in the first stage of processing and is the raw material for titanium processing materials. Natural forms of titanium are widespread in the earth's crust. After extraction, it is processed to remove excess material and convert it into a usable but expensive product.
It is a simple substance of titanium metal, usually in the form of light gray particles or sponges. It is the basic raw material for titanium materials, titanium powder and other titanium products. It turns ilmenite into titanium tetrachloride and reacts with metal magnesium to obtain sponge-like porous "Titanium Sponge".
Development history of titanium sponge
At the end of the 18th century, the British clergyman and amateur mineralogist William Gregor and the German chemist M.H. Klaproth came from the same place in 1791 and 1795 respectively. A new element was discovered in a black magnetite sand (later learned to be titanium magnetite) and a non-magnetic oxide mineral (later learned to be natural rutile ore), which they called "Monaquin" respectively. " (the name of the place where titanium magnetite was found) and "titanium clay". A few years later, it was proven that the so-called "menacun" and "titanium" found in these two minerals were actually oxides of the same element, and this new species was named after the Titans (Titans), the Hercules in Greek mythology. The element is "Titanium".
The three most important parts of titanium sponge production
1) The high titanium slag is chlorinated to generate titanium tetrachloride. This part can be completed by using the modified device of the existing chlorination titanium dioxide production line in the titanium dioxide factory;
2) The reduction and distillation of titanium tetrachloride, that is, the magnesium thermal method, is to react the refined titanium tetrachloride with molten magnesium at high temperature to obtain sponge-like metallic titanium and molten magnesium chloride, and then use vacuum distillation to remove the sponge titanium. of magnesium chloride and excess magnesium to obtain pure titanium;
3) The magnesium chloride is melted and electrolyzed in an electrolytic tank to obtain molten metal magnesium and chlorine gas, which are then sent back to the reaction raw materials in the previous section for use.
