Reaction of titanium with air. Titanium metal is coated with an oxide layer that usually renders it inactive. However once titanium starts to burn in air it burns with a spectacular white flame to form titanium dioxide, TiO 2 and titanium nitride, TiN. Titanium metal even burns in pure nitrogen to form titanium nitride.

This problem was overcome in 1940 with a combined HF-HCl treatment. The HF in the acid combination dissolves mineral deposits in sandstones that hinder production, while the HCl controls precipitates.
