The titanium metallurgy raw materials used in industrial production are mostly rutile (TiO 2) and ilmenite (FeTiO 3).Rutile has high grade but small reserves. Ilmenite has abundant reserves but low grade of titanium dioxide, so reduction smelting is needed to enrich it into a titanium-rich material, i.e., high titanium slag or artificial rutile.

Porous structures at both the surface layer and inside were formed at intervals of about 5.0 × 10-5 m. When the titanium nitride sponge was immersed into a titanium alloy melt, the melt permeated into the pores. The dissolution rate of the titanium nitride sponge in the titanium alloy melt depends on the temperature of the melt.
