Zirconium hydride an ore, usually a zirconium silicate, such as zircon. Zirconium is extracted from zirconium ore by removing the oxygen and silica. This process, known as the Kroll process, was first applied to titanium. The Kroll process results in an alloy containing hafnium. The hafnium and other impurities are removed in a subsequent step. Zirconium hydride is created by combining refined zirconium with hydrogen. Like titanium, solid zirconium dissolves hydrogen quite readily. The density of zirconium hydride varies based the hydrogen and ranges between 5.56 and 6.52 g cm. Even in the narrow range of concentrations which make up zirconium hydride,
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
