Zirconium nitrate of chemical suppliers. It is used as a source of zirconium for other salts, as an analytical standard, or as a preservative. Zirconium nitrate and nitronium pentanitratozirconate can be used as chemical vapour deposition precursors as they are volatile, and decompose above 100 °C to form zirconia. At 95°C zirconium nitrate sublimes with a pressure of 0.2 mm of Hg and can be deposited as zirconium dioxide on silicon at 285°C. It has the advantage in that it is a single source, meaning it does not have to be mixed with other materials like oxygen, and decomposes at a relatively
Diamonds as an investment the De Beers cartel in 2001, the industry is now more fragmented resulting in a higher percentage of diamond sales taking place in the form of auctions and other forms of open-market sales. Since the 1950s, techniques can produce diamonds of essentially any desired chemistry or size. and with fewer flaws than natural diamonds have. Although some manufacturers do label their synthetic diamonds with serial numbers there is no guarantee that a given diamond is not man made, although sometimes an unnatural chemical composition or pattern of flaws may suggest a diamond is synthetic. It is much cheaper to produce
