What is the main purpose of zirconium hydride?
What is Zirconium hydride?
Zirconium hydride is an inorganic compound with the chemical formula of ZrH 2, which is mainly used as a high-purity analytical reagent, hydrogenation catalyst, strong reducing agent, and hydrogenation agent, and can also be used as a non-smoking ignition powder.

Physicochemical property of Zirconium hydride Powder
According to the purity of hydrogen used, the product composition is ZrH2-xo. There are two forms of zirconium hydride ZRH1.6 and ZRH2. The room-temperature type is an oblique fluorite square crystal, and the high-temperature type is a fluorite cubic crystal. Because hydrogen occupies a certain position in the crystal lattice, not only interstitial compounds are formed, but also zirconium hydride, δ-type (face-centered cubic crystal, composition range of ZrH1.44～ZrH1.65), and γ-type (composition range of ZrH0.05～ZrH1.36).
The appearance of zirconium oxide is metallic, and the powder is black. The relative molecular mass is 93.24. The relative density is 5.74. The heat of formation is 124kJ/mol. Conductivity is between metal and semiconductor. When the pressure drops to 1.33×10-3Pa, Hydrogen is released at 400℃ and becomes metal.
Zirconium hydride has no hygroscopicity and is Stable in the air. It does not react to water and weak acids under normal circumstances and is easily soluble in 1% ~ 5% hydrofluoric acid. It can react violently with oxidants and strong acids. When it is ignited, it can burn smoothly. Heating to 500 ~ 700℃ almost completely decomposes.
Uses of Zirconium hydride
1. Zirconium hydride can be used as a strong reducing agent.
2. Used as an additive
3. Deoxidizer and desulfurized in preparation of ferroalloy.
4. Mixed with calcium carbide and nitride, it can be used as a metal coating.
5. Because it can wet ceramics, it is used as a metal-ceramic adhesive for vacuum tubes and ceramic devices.
6. In addition, it is used as a neutron moderator and other materials of the atomic power station, getters of vacuum tubes, fire traps, flux, and so on.
Production method of Zirconium hydride
Sponge metal zirconium with a purity of 99.8% and high purity hydrogen (99.9999%) is heated to 400 ~ 600℃ and directly reacted to obtain the product. The reaction is exothermic. Or zirconium dioxide can be reduced with calcium hydride at 600℃ in hydrogen flow.
Price of Zirconium hydride Powder
Zirconium hydride powder particle size and purity will affect the product's price, and the purchase volume can also affect the cost of Zirconium hydride powder. A large amount of large amount will be lower. The price of Zirconium hydride powder can be found on our company's official website.
