Useful:

• Physical properties: Grayish-black metallic powder; stable in air; density 3.75 g/cm3; decomposes at 450°C with evolution of hydrogen; insoluble in water.
• Uses: Additive in powder metallurgy; getter for oxygen and nitrogen in electronic tubes; wetting agent for ceramic to metal seals; source of pure hydrogen. Titanium(II) hydride is widely utilized as an additive in the manufacturing of Alnico sintered magnets and in sintered powdered metals. It is used in the production of metal foam, powdered titanium metal and in pyrotechnics. It is involved in various applications such as ceramics, pyrotechnics and sports equipment. It is also used as a laboratory reagent and as a blowing agent.

Technology Process of Titanium hydride

There total 3 articles about Titanium hydride which guide to synthetic route it. The literature collected by LookChem mainly comes from the sharing of users and the free literature resources found by Internet computing technology. We keep the original model of the professional version of literature to make it easier and faster for users to retrieve and use. At the same time, we analyze and calculate the most feasible synthesis route with the highest yield for your reference as below:

synthetic route:

Reference yield:

titanium (7440-32-6) + hydrogen (1333-74-0) + oxygen (80937-33-3) → titanium(IV) hydroxide (20338-08-3) + titanium dihydride (7704-98-5) + [TiH(OH)3] (956378-98-6) + titanium dihydroxide (42765-12-8) + HTiO(OH)

Guidance literature:

In neat (no solvent); Irradiation (UV/VIS); laser ablated Zr co-deposited with H2+O2 in excess Ar onto a 10K CsI window, UV-irradiated, annealed at 22-34 K (mechanism discussed); not isolated, detected by IR;

Reference yield:

titanium (7440-32-6) + hydrogen (1333-74-0) + oxygen-18 (32767-18-3) → titanium dihydride (7704-98-5) + Ti((18)OH)2 (872215-20-8) + HTi(18)O((18)OH) + HTi((18)OH)3 + Ti((18)OH)4 (872207-84-6)

Guidance literature:

In neat (no solvent); laser ablated Zr co-deposited with H2+(18)O2 in excess Ar onto a 10K CsIwindow, annealed at 20 K (mechanism discussed); not isolated, detected by IR;

DOI:10.1021/jp054482i

Reference yield:
