摘　　要：介绍了石膏及硬石膏的结构及性质。石膏可深加工成α－半水石膏、石膏超细粉及硫酸钙晶须等。α－半水石膏较常用的β－半水石膏凝结强度大得多；石膏超细粉可作塑料、橡胶填料及造纸涂料；硫酸钙晶须可用于塑料、橡胶。The structures and properties of gypsum and anhedritite are introduced in this paper. Gypsum can processing into α semi hydrated gypsum,ultrafine gypsum powder and calcium sulfate whiskers etc.. The coagulating strength of α semi hydrated gypsum is much greater than β semi hydrated gypsum. Ultrafine gypsum powder can be used as fillers for plastics and rubbers or paper paint. Calcium sulfate whiskers can be used in fields of plastics,rubbers,adhesive and friction materials etc..
