Titanium sponge is a form of titanium that is brittle and porous in nature. It shows high elasticity, with a high strength-to-weight ratio. It is utilized as a base for titanium billets, alloys, ingots, and others. Moreover, it shows low electrical and thermal conductivity and is one of the usual corrosion-resistant structural metals.Titanium sponge is achieved by the administration of the Kroll process on raw titanium ore. The obtained titanium sponge has various impurities. These impurities usually are nitrogen, hydrogen, chlorine, silicon, oxygen, iron magnesium, among others.
