titanium hydride

[tī′tā·nē·əm ′hī‚drīd]
(inorganic chemistry)
TiH2 A black metallic powder whose dust is an explosion hazard and which dissociates above 288°C; used in powder metallurgy, hydrogen production, foamed metals, glass solder, and refractories, and as an electronic gas getter.

Vanadium hydride decomposes at 200[degrees]C, and titanium hydride Ti[H.sub.2] is stable in the interval of experimental temperatures [30].
Vanadium and titanium hydrides are deemed to be promising as solid state hydrogen storage.
The second option for improving the thermodynamic characteristics of vanadium and titanium hydrides is aimed at forming more "dense" VN fcc-lattice instead of "loose" bcc-vanadium lattice and TiN fcc-lattice instead of hcp-titanium lattice.
As applied to the high-usage production methods based on handling of a melt and powder compact technique [4,10] economical limitation arises particularly due to the employing of costly conventional foaming agent, titanium hydride (Ti[H.sub.2]).
All kinds of Al-foams were produced via Alporas like route in which either titanium hydride Ti[H.sub.2] or calcium carbonate CaC[O.sub.3] were employed as foaming agents [9, 14, 15].
In a and a-a alloys, excessive hydrogen uptake can induce the precipitation of titanium hydride in the a phase.
Under strongly reducing (cathodic) conditions, titanium hydride formation is predicted.
This process, developed at the Fraunhofer Institute for Manufacturing and Advanced Materials, belongs to the processes starting from metal powders as raw material with an addition of the titanium hydride as the foaming agent [2].
The process is based on mixing aluminium (Al), titanium hydride (Ti[H.sub.2]) and silicon carbide (SiC) powders to obtain an homogeneous mixture, followed by compression into a preform (foamable precursor material), and foaming of the preformed sample in a furnace.
Titanium hydrides are well known for their catalytic activity in many reactions including polymerization of olefins and nitrogen fixation (1).
