摘　　要： 硫酸钙晶须是一种性能优良、价格低廉的绿色环保材料。制备硫酸钙晶须主要采用天然石膏为原料,而天然石膏是不可再生资源,无限开采将导致天然石膏资源的枯竭,目前中国已开始利用工业副产品制备硫酸钙晶须的研究。阐述了硫酸钙晶须的制备原理,以及利用天然石膏与工业副产品制备硫酸钙晶须的现状。提出了利用工业副产品制备硫酸钙晶须既能保护天然石膏资源,又能实现资源循环再生,将是今后的发展趋势。 Calcium sulfate whisker is a green environment-friendly material of excellent properties and low in price. It mainly abopts natural gypsum to produce calcium sulfate whisker, but natural gypsum is non - renewable resource. Therefore unlimited mining will lead to exhaustion of natural gypsum resources. There a/ready has some researches on producing calcium sulfate whisker by using industrial by-product gypsum in China. Through expounding preparation principle of calcium sulfate whisker, and present situation of producing calcium sulfate whisker by using natural gypsum and industrial by-product gypsum, it was put forward that utilizing industrial by-product to prepare calcium sulfate whisker can protect natural gypsum resourse, as well as can realize resources regeneration, and it will be the future development tendency.
