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 lactate It is suspected of causing zirconium granulomas (a form of skin irritation) in a small number of users. Zirconium lactate Zirconium lactate is a zirconium complex derived from lactic acid. It is used in some deodorants. It is a colourless solid. Zirconium carboxylates adopt highly complex structures and are heterogeneous compositions with the approximate formula Zr(OH)(OCCHOHCH)(HO) where 1 < n < 3. It is also used in the petroleum industry as a cross-linking agent to prepare gels for fracturing fluids, fluids which are pumped into an oil-bearing rock formation to cause cracks in the rock and so to allow the
