摘要
综述了国内外α半水石膏的制备现状,分析了磷石膏制备高强α半水石膏的研究进展;指出用磷石膏水热法制备高强α半水石膏的研究重点是从磷石膏所含杂质和原始结晶形态出发,研究相应的转晶技术和机理。
Situations of preparation of α-hemihydrate at home and abroad are discussed through consulting a large number of literature. Research progress of the production of high-strength α-hemihydrate gypsum by phosphogypsum is studied,then that technology and mechanism of α-hemihydrate gypsum crystal transition with the hydrothermal method based on the impurities and initial crystal morphology of phosphogypsum will be research emphases is pointed out.
