Zirconium tetrafluoride reactors.) Zirconium tetrafluoride Zirconium(IV) fluoride (ZrF) is an inorganic chemical compound. It is a component of ZBLAN fluoride glass. It is insoluble in water. It is the main component of fluorozirconate glasses. Three crystalline phases of ZrF have been reported, α (monoclinic), β (tetragonal, Pearson symbol tP40, space group P42/m, No 84) and γ (unknown structure). β and γ phases are unstable and irreversibly transform into the α phase at 400 °C. Zirconium fluoride is used as a zirconium source in oxygen-sensitive applications, e.g. metal production. Zirconium fluoride can be purified by distillation or sublimation. Conditions/substances to avoid are: moisture,
Zirconia alumina Zirconia alumina Zirconia alumina is commonly used as a sand-blasting medium. It is typically used as an abrasive in casting and foundry processes. Zirconia alumina is a mixture of zirconium dioxide and aluminium oxide. Zirconia toughened alumina typically consists of alumina with a 10 to 20 percent zirconia concentration, which enhances the toughness of the alumina. To achieve the increase in the composite’s strength, a process known as stress induced transformation toughening takes place. Stress induced transformation toughening results in uniform internal strain, which causes the zirconia structure to crack, and the zirconia particles to switch phases. Because of this
