Zirconium hydride an ore, usually a zirconium silicate, such as zircon. Zirconium is extracted from zirconium ore by removing the oxygen and silica. This process, known as the Kroll process, was first applied to titanium. The Kroll process results in an alloy containing hafnium. The hafnium and other impurities are removed in a subsequent step. Zirconium hydride is created by combining refined zirconium with hydrogen. Like titanium, solid zirconium dissolves hydrogen quite readily. The density of zirconium hydride varies based the hydrogen and ranges between 5.56 and 6.52 g cm. Even in the narrow range of concentrations which make up zirconium hydride,
Zirconium(IV) bromide Zirconium(IV) bromide Zirconium(IV) bromide is the inorganic compound with the formula ZrBr. This colourless solid is the principal precursor to other Zr–Br compounds. ZrBr is prepared by the action of bromine on zirconium oxide via a carbothermic reaction: Like many related tetrahalides, it is purified by sublimation. Like related tetrabromides of Ti and Hf, ZrBr hydrolyzes readily to give oxy-bromide, with release of hydrogen bromide. No single crystal X-ray study of ZrBr has been described. Some reports suggest that it is isostructural with TiCl and TiBr, featuring tetrahedral metal centers. Other studies indicate a polymeric structure. ZrCl is polymeric in
