Zirconium perchlorate as cold as possible. Zirconium perchlorate is very hydroscopic forming hydrates, and it is hydrolysed by water to yield zirconyl perchlorate, ZrO(ClO). Zirconium perchlorate reacts with vaseline, methyl nitrate or acetonitrile. Zirconium perchlorate is inert towards carbon tetrachloride, chloroform, and dimethylformamide. Zirconium perchlorate reacts with benzene at 20°C, but at -10°C crystals of Zr(ClO)•CH are deposited. Zirconium perchlorate has solid state transition around 45°C, a melting point between 95.5 and 96.0°C and a decomposition point starting around 120°C. The zirconyl perchlorate formed in the heat decomposition, itself decomposes around 290°C to form zirconia, chlorine and oxygen. In the gas phase
Cubic zirconia diamond: Cubic zirconia, as a diamond substituent and jewel competitor, has been seen as a potential solution against conflict diamonds and the controversy surrounding the rarity and value of diamonds. Regarding the latter, the main argument presented being that the paradigm where diamonds were seen as rare due to their visual beauty is no longer the case and instead has been replaced by an artificially rarity reflected in their price. This is attributed to confirmed evidence that there were price-fixing practices taken by the major producers of rough diamonds, in majority attributed to De Beers Company known as to holding
