Abstract: |
|||
| This invention is aimed at providing a process which is imple in technology and suitable for industry application to produce sandish aluminium oxide by carbonating decomposition in soda-lime sintering process. Its main technical features are: by adopting cycling of inoculating crystal, the reievant another process for prepg. inocuiating crystal of aluminium hydroxide is not required also the maintaining for constant temp. of slurry is not needed in decomposition reaction. The said technological process is simple, low cost and suitable for industry application. | |||
