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.
Uses of Zirconium hydride powder Zirconium hydride is a strong reducing agent. Used as an additive. Deoxidizer and desulfurized in preparation of ferroalloy. Mixed with calcium carbide and nitride, it can be used as a metal coating. Because it can wet ceramics, it is used as a metal-ceramic adhesive for vacuum tubes and ceramic devices. In addition, it is used as a neutron moderator and other materials of the atomic power station, getter of the vacuum tube, fire trap, flux, and so on. Physical and chemical properties of Zirconium hydride 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 hydride 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. No hygroscopicity. Stable in the air. It does not react to water and weak acid 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. Properties of Zirconium hydride The chemical formula of zirconium hydride is ZrH2, the density is 5.6g/cm3, and it decomposes before melting to generate heat of -39.7kcal/mol. Its preparation method is the same as that of titanium hydride, and the hydrogenation reaction is often carried out at 900℃. It is a stable powder, which is stable to air and water under normal conditions. It can react violently with oxidants and strong acids, and it can burn smoothly when it is ignited. It starts to decompose at 300℃ in a vacuum and completely decomposes at 500-700℃. 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.
