摘要
利用氟石膏、氯化钾为原料，采用碳铵为中间体的间接法工艺制备硫酸钾，研究了影响工艺过程的因素。
Potassium sulfate was prepared with fluorogypsum and potassium chloride as raw material, ammorium bicarbonate as intermediate. The factors which affected the technology process were studied. The conversion rates of both SO 4 2- and k + were over 75 %.
