Zirconium nitrate of chemical suppliers. It is used as a source of zirconium for other salts, as an analytical standard, or as a preservative. Zirconium nitrate and nitronium pentanitratozirconate can be used as chemical vapour deposition precursors as they are volatile, and decompose above 100 °C to form zirconia. At 95°C zirconium nitrate sublimes with a pressure of 0.2 mm of Hg and can be deposited as zirconium dioxide on silicon at 285°C. It has the advantage in that it is a single source, meaning it does not have to be mixed with other materials like oxygen, and decomposes at a relatively
Zirconium(II) hydride the atomic number increases. Zirconium(II) hydride Zirconium(II) hydride, ZrH is a molecular chemical compound which has been prepared by laser ablation and isolated at low temperature. Zirconium(II) hydride has repeatedly been the subject of Dirac–Hartree–Fock relativistic calculation studies, which investigate the stabilities, geometries, and relative energies of hydrides of the formula MH, MH, MH, or MH. Zirconium(II) hydride has a dihedral (C) structure. In zirconium(II) hydride, the formal oxidation states of hydrogen and zirconium are −1 and +2, respectively, because the electronegativity of zirconium is lower than that of hydrogen. The stability of metal hydrides with the formula MH (M
