Titanium hydride normally refers to the inorganic compound TiH 2 and related nonstoichiometric materials. [1] [2] It is commercially available as a stable grey/black powder, which is used as an additive in the production of Alnico sintered magnets, in the sintering of powdered metals, the production of metal foam, the production of powdered titanium metal and in pyrotechnics.
Titanium(IV) hydride (systematically named titanium tetrahydride) is an inorganic compound with the empirical chemical formula TiH 4. It has not yet been obtained in bulk, hence its bulk properties remain unknown. However, molecular titanium(IV) hydride has been isolated in solid gas matrices.
The +4 oxidation state dominates titanium chemistry, [1] but compounds in the +3 oxidation state are also numerous. [2] Commonly, titanium adopts an octahedral coordination geometry in its complexes, [3] [4] but tetrahedral TiCl 4 is a notable exception. Because of its high oxidation state, titanium(IV) compounds exhibit a high degree of ...
A metal hydride can be a thermodynamically a weak acid and a weak H − donor; it could also be strong in one category but not the other or strong in both. The H − strength of a hydride also known as its hydride donor ability or hydricity corresponds to the hydride's Lewis base strength. Not all hydrides are powerful Lewis bases.

Orthotitanates have the formula M 2 TiO 4, where M is divalent.An example of such a material is magnesium titanate (Mg 2 TiO 4), which adopts the spinel structure.Li 2 TiO 3 is not considered an orthotitanate since it adopts the rock-salt structure and does not feature an identifiable titanium anion.
When sodium hydride is compressed with hydrogen, NaH 3 and NaH 7 form. These are formed at 30 GPa and 2,100 K. [2] Heating and compressing a metal with ammonia borane avoids using bulky hydrogen, and produces boron nitride as a decomposition product in addition to the polyhydride.
