Description :
Titanium hydride describes an alloy made by combining titanium and hydrogen. Hydrogen acts as a softening agent, allowing dislocations in the titanium atom crystal lattice to slide past one another. Varying the amount of hydrogen controls qualities such as the hardness, and tensile strength of the resulting titanium hydride. Titanium hydride with increased hydrogen content can be made softer than titanium.
In the narrow range of concentrations which make up titanium hydride, mixtures of hydrogen and titanium can form two different structures. At room temperature, the most stable form of titanium is the hexagonal close-packed (HCP) structure α-titanium. It is a fairly hard metallic material that can dissolve only a small concentration of hydrogen, no more than 0.2 wt% at 610 °C, and close to 0.0% at 25 °C. If titanium hydride contains more than 0.0% hydrogen at room temperature, then it transforms into a face-centred cubic (FCC) structure called the δ-phase. It can dissolve considerably more hydrogen, as much as 4.04% hydrogen, which reflects the upper hydrogen content of titanium hydride.[1]
It is highly reactive and needs to be kept away from heat and strong oxidizers.
Titanium hydride is used with potassium perchlorate in some igniter pyrotechnic compositions and flash powders. It also can be used to create hydrogen and titanium hydroxide. It is created by the reaction of titanium and hydrogen.
USES :
Titanium hydride has several uses. It is used as a foaming agent in production of metal foams. It is also used to coat badminton racket strings to improve durability.
