The aluminium borate was synthesized by the raw materials of alum and boric acid in the meting potassium sulfate. The dissolution experiments for the K2SO4 from the block. Such as water, different concentrations of HCl and H2SO4, and temperatures, stirring rates, respectively have been conducted. Al9B4O33 was separated and identified by X-Ray powder diffration analysis. This paper reports the favorable condition for preparation aluminium borate and for recovery of K2SO4. |
