摘　　要：利用磷石膏与钛石膏混烧工艺,解决钛石膏处理难问题。将磷石膏中混掺10%的钛石膏,放入沸腾炉中进行煅烧,制备出合格的建筑石膏粉。该种石膏粉具有良好的初凝时间与终凝时间,同时标准稠度的需水量较低,石膏的抗折抗压强度较高,可广泛地应用于抹灰石膏、石膏基自流平等石膏制品。The difficult problem of titanium gypsum treatment was solved by the mixed firing process of phosphogypsum and titanium gypsum. The qualified building gypsum powder was prepared by mixing 10% titanium gypsum in phosphogypsum and calcination in boiling furnace. This kind of gypsum powder has good initial setting time and final setting time, at the same time, the water requirement of standard consistency is low, the flexural compressive strength of gypsum is high, and it can be widely used in plastering gypsum and gypsum base self-leveling gypsum products.
