| Abstract: |
| The coarse aluminum hydroxide is produced by sodium bicarbonate solution precipitating Bayer refined solution, the influences of the precipitation time, temperature, rules, rate, sodium bicarbonate solution concentration and Byer seed on aluminum hydrate particle size are studied, the percentage of <45 μm powder could decrease to 9.94% under the proper process conditions. |
