| Abstract: | The soluble aliminum hydroxide was prepared by seed precipitation method. The effects of decomposition solution concentration, the amount of seed crystal and decomposi- tion temperature On the decomposition rate of the sodium aluminate solution and the alumi- num hydroxide acid soluble have been studied. Under the optimum conditions the initial and final decomposition temperature was 40 and 30℃, respectively; the decomposition solution concentration of A12O3 was 130 g/L and the amount of seed crystal was 0.4 g/L, the acid soluble rate of the product was more than 90%. The morphology and crystal structure of the product were characterized by SEM and XRD. |
