Zirconium dioxide for aesthetic reasons, or of 2) strong, extremely durable dental prostheses constructed entirely from monolithic zirconia, with limited but constantly improving aesthetics. Zirconia stabilized with yttria (yttrium oxide), known as yttria-stabilized zirconia, can be used as a strong base material in some full ceramic crown restorations. Transformation toughened zirconia is used to make ceramic knives. Because of the hardness, ceramic-edged cutlery stays sharp longer than steel edged products. Due to its infusibility and brilliant luminosity when incandescent, it was used as an ingredient of sticks for limelight. Zirconia has been proposed to electrolyze carbon monoxide and oxygen from the atmosphere
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
