• Uses: Zirconium Hydride, ZrH2, is a brittle, metallicgray solid that is stable in air and water, and has a density of 5.6 g/cm3. The chemical properties of ZrH2 closely resemble those of titanium hydride. Commercial uses are as a getter in the manufacture of vacuum tubes and other systems; as a hydrogen source for foaming metals; as a hydrogen reservoir; for the introduction of zirconium into powdered alloys; for metal–ceramic and metal–metal bonding; as a moderator in nuclear reactors; and as a source of Zr metal powder and alloys. Zirconium hydride is a powerful reducing agent in acid solution or at high temperatures; hydrogenation catalyst; in the vacuum tube industry.Also, it is used as a source of pure hydrogen and a catalyst in hydrogenation reactions. Some other applications are in powder metallurgy; as a moderator in nuclear reactors; and as a metal-foaming agent Zirconium(II) hydride (ZrH2) can be used as a precursor for:?Reactive hot-pressing synthesis of Zr2SC ceramics by displacement reaction with the mixture of ZrC and ZrS2.,·??The synthesis of Mg-Zr hydrides by treating with MgH2 for hydrogen storage.??????? The preparation of layer structured β-zirconium nitride chloride (ZrNCl) by reacting with NH4Cl.
