Description

Brief Description of TiH2 Hydride Titanium

Titanium hydride normally refers to the inorganic compound TiH2 and related nonstoichometric materials.It is commercially available as a stable grey/black powder.

In the commercial process for producing non-stoichiometric TiH(2-x), titanium metal sponge is treated with hydrogen gas at atmospheric pressure at between 300-500 °C. Absorption of hydrogen is exothermic and rapid, changing the color of the sponge grey/black.

The brittle product is ground to a powder, which has a composition around TiH1.95.

In the laboratory, titanium hydride is produced by heating titanium powder under flowing hydrogen at 700 °C, the idealized equation being:

Ti + H2 → TiH2

Other methods of producing titanium hydride include electrochemical and ball milling methods

Structure of TiH2 Hydride Titanium

As TiHx approaches stoichiometry, it adopts a distorted body-centered tetragonal structure, termed the ε-form with an axial ratio of less than 1.

This composition is very unstable with respect to partial thermal decomposition, unless maintained under a pure hydrogen atmosphere.

Otherwise, the composition rapidly decomposes at room temperature until an approximate composition of TiH1.74 is reached.

This composition adopts the fluorite structure, and is termed the δ-form, and only very slowly thermally decomposing at room temperature until an approximate composition of TiH1.47 is reached, at which point, inclusions of the hexagonal close packed α-form, which is the same form as pure titanium, begin to appear.

Storage of TiH2 Hydride Titanium

Should be stored in shady, cool and ventilated warehouse.

Kept far away from fire, heat source and acid.

No smoking in the workplace.

Fire fighting equipment such as extinguisher should be available.

Should be stored in vacuum encapsulation in case of being oxidized.
