Titanium sponge is an elemental form of titanium that typically appears as light grey particles or a sponge-like mass. It serves as the fundamental raw material for the production of titanium materials, titanium powder, and other titanium products. Sponge titanium is obtained by transforming titanium ore into titanium tetrachloride, which is then reacted with metallic magnesium to yield a porous, sponge-like mass.

During the reduction and distillation process, impurities can be introduced into the titanium sponge lump due to a variety of factors, including temperature, pressure, furnace condition, and segregation. According to the Chinese standard GB/T 2524, titanium sponges can be classified into seven grades, ranging from MHT 95 to MHT 200, with the number referring to the Brinell hardness maximum value. The general purity (%) quality is 98.5 to 99.8, and the impurity element oxygen quality (%) ranges from 0.05 to 0.30. The hardness (HB) of sponge titanium ranges from 95 to 200.
