Zirconium dioxide of Mars to provide both fuel and oxidizer that could be used as a store of chemical energy for use with surface transportation on Mars. Carbon monoxide/oxygen engines have been suggested for early surface transportation use as both carbon monoxide and oxygen can be straightforwardly produced by zirconia electrolysis without requiring use of any of the Martian water resources to obtain hydrogen, which would be needed for the production of methane or any hydrogen-based fuels. Zirconia is also a potential high-k dielectric material with potential applications as an insulator in transistors. Zirconia is also employed in the deposition of optical
Zirconium(IV) bromide the solid state, featuring octahedral Zr centers. 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
