"The preparation of zirconium powder by several different methods is fully described and evaluated. Most of the methods described are of a rather classical nature and these methods are discussed as taken from their original sources with suggestions for possible streamlining. Flow sheets are provided. The first series of steps to produce zirconium powder is almost invariably the production of ...
Nov 10, 2006· Nanocrystalline zirconia samples having predominantly tetragonal crystalline phase were synthesized using sol−gel and conventional precipitation techniques from zirconium hydroxide obtained by the hydrolysis of both zirconium propoxide and zirconium oxychloride precursors. Thermal drying of zirconium hydroxide gel in an oven (110 °C, 12 h) results in lower crystallite size (11−13 nm) as ...
