Title: Production of hydrated zirconia powder
Inventor: AIMOTO MICHIYUKI
IPC: C01G25/02
Filed: 1993-04-01
Abstract: PURPOSE:To obtain hydrated zirconia powder free from generation of hydrogen chloride gas at normal temperature to eliminate the troubles of the corrosion of production apparatuses and the deterioration of environment during the steps up to the calcination step by drying a hydrated zirconia sol produced by the hydrolysis of zirconium oxychloride and contacting the obtained dry powder with ammonia gas.
