Report Abuse. Titanium is a solid at normal conditions (a metal). It is not found in nature as a pure element rather in its oxide form rutile, principally in commercial concentrations in beach sands along the coast of Queensland.
Titanium burns in air and is the only element that burns in nitrogen. Titanium is dimorphic, with the hexagonal a form slowly changing to the cubic b form around 880Â°C. The metal combines with oxygen at red heat temperatures and with chlorine at 550Â°C. Titanium is as strong as steel, but it is 45% lighter.
