Titanium hydride powder, The product is a dark gray irregular powder. Use Titanium powder and Titanium Hydrogenate Powder are a very widely used metal powder. The oxidation state +4 is the dominant in titanium chemistry, but compounds with an oxidation state of +3 are also common. Because of such high oxidation states, the covalent bonds in many titanium compounds are highly dense.
