Do you understand what is titanium sponge?

- Dec 12, 2017 -

Sponge titanium refers to the use of magnesium or sodium reduction of titanium tetrachloride to obtain a purity of 98.5% -99.7% spongy titanium metal. Titanium is the most important raw material in industrial production. Titanium sponge is a primary product in the whole titanium metal production, which needs to be further cast to obtain titanium ingots, namely industrial pure titanium, which can then be processed into corresponding titanium materials such as titanium rods, titanium tubes, titanium wires, titanium targets and the like .

Preparation of sponge titanium: At present, the industry mainly Magnesium thermal reduction (Kroll) method, sodium thermal reduction method (Hunter method) and molten salt electrolysis. Magnesium reduction method has the advantage of reducing magnesium can be recycled, a single furnace capacity. In contrast, sodium pyrogen reduction product quality is better, low levels of metal impurities, but a single furnace production capacity, sodium consumption. The molten salt electrolysis is still in the semi-industrial test phase.
