| Abstract: | Alpha-hemihydrate gypsum was prepared with hydrothermal method under atmospheric pressure using the desulfurization gypsum as raw materials. The influences of salt solution concentration, reaction temperature, solid-liquid ratio and pH value on the morphology and transformation rate of the hemihydrate gypsum were studied. The sensitivity analysis of each factor was carried on. The results show that the concentration of salt solution was the most important factor. The sensitivity of each factor was: concentration > pH value > temperature > solid-liquid ratio. |
