Titanium Hydride, Grade T (CAS 7704-98-5, molecular formula TiH2) is an inorganic chemical supplied as a technical-grade material. It is typically a grey to black powder.

Titanium hydride powders find application in both pyrotechnic and metallurgical areas. They are utilized in initiator squibs and igniters. They are also used as getters in the manufacture of vacuum tubes, as brazing aids in sealing ceramics to metals, the introduction of titanium to alloys; as reservoir for pure hydrogen; as hydrogen source for foaming metals; as a deoxidizing agent and for the absorption of carbon in powder metallurgy; for the production of Ti alloys and semi-finished sintered articles; as a constituent in AlNiCo and TiCoNaI sintered magnets; used for increasing the coercivity of FeNiCoAlCu magnets.

Typical specifications include: Ignition Gain min. 58.0 %; Ti total min. 94.8 %; Hydrogen min. 3.8 %.

Applications

Titanium hydride powders find application in both pyrotechnic and metallurgical areas. They are utilized in initiator squibs and igniters. They are also used as getters in the manufacture of vacuum tubes, as brazing aids in sealing ceramics to metals, the introduction of titanium to alloys as reservoir for pure hydrogen as hydrogen source for foaming metals as a deoxidizing agent and for the absorption of carbon in powder metallurgy for the production of Ti alloys and semi-finished sintered articles as a constituent in AlNiCo and TiCoNaI sintered magnets used for increasing the coercivity of FeNiCoAlCu magnets.

Handling and Storage

Handling Instructions

Highly flammable solid. Dust explosion hazard. Stable titanium hydride powder of high purity, yielding hydrogen at elevated temperatures in a reversible reaction; easily pressed and sintered. Like Ti metal, TiH2 is resistent to most chemical reagents, but is attacked at elevated temperature by oxidizing agents and acids. TiH2 is attacked by cold hydro fluoric acid solutions. Safe to handle at room temperature. At elevated temperatures and low pressures the generation of hydrogen must be considered. Risk of dust explosion. In case of fire cover with dry sand or dry chemical/dolomite (powdered limestone). Never extinguish with water, carbon dioxide, or halocarbon.
