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,
Cubic zirconia a monopoly on the market from the 1870s to early 2000s. The company plead guilty to these charges in an Ohio court in 13 July 2004. However, De Beers and Co do not have as much power over the market, the price of diamonds continues to increase due to the increased demand in emerging markets such as India and China. Therefore, with the emergence of artificial stones, such as cubic zirconia, that have optic properties highly similar to that of diamonds (see section above), it has been presented that these could be a better alternative for jewelry buyers given their
