研究反应温度、酸浓度、溶剂浓度及搅拌速度对硫酸钙结晶过程的影响 ;在溶剂中加入活性添加剂后 ,硫酸钙的溶解度增大 ,晶形由细长瓦楞状变成了粗大棱柱状。
The effects of reaction temperature, acid concentration, solvent concentration and stirring speed on the crystallization process of calcium sulfate were studied. The solubility of calcium sulfate increased after the active additives were added into the solvent, and the crystal form changed from slender corrugated to coarse prism.
