反応手順
European Patent No. 369,979 (1989) discloses a way of making fine spherical powders of amorphous hydrated zirconium oxide. In the given example, a process was described in which zirconium oxychloride octahydrate (ZrOCl2.8H2O) was dissolved in 2-methoxyethanol at 60° C. and it was claimed that water was removed as an azeotropic mixture of water and 2-methoxyethanol to produce an essentially anhydrous zirconium salt. It was further claimed that to this zirconium salt was added n-propanol followed by the successive additions of propylene oxide and triethylamine to afford an organic solution of zirconium propoxide. This intermediate zirconium compound was then treated with a mixture of water, oleic acid and n-propanol to effect the hydrolysis and to produce spherical particles of zirconium oxide.
