磷石膏晶须的制备及应用研究进展

The Research Progress of Manufacture and Application of Gypsum Whiskers

硫酸钙晶须本身是一种性能优良,价格低廉的绿色环保材料,但是由于制备硫酸钙晶须主要采用不可再生的天然石膏为原料,长期开采必将导致石膏资源的枯竭。目前中国已经开始了利用工业副产品生产石膏晶须的研究,重点阐述了磷石膏晶须的制备进展,指出了针对当前湿法磷酸过程中产生的堆积如山的磷石膏,充分利用磷石膏生产磷石膏晶须,将会是今后的一个主要趋势,市场潜力巨大。

Calcium sulfate whisker（CSW） was an excellent,low price and green materials.Since the main use of non-renewable natural gypsum as raw materials,long-term exploitation of resources would inevitably lead to depletion of gypsum.At present,China used industrial by-product production of gypsum whisker to research focuse on the progress of phosphogypsum whiskers,pointed out that the current generated in the process of WPA mountains of phosphogypsum,full use of phosphorus gypsum production gypsum whisker would be a major trend in the future,and the market had great potential.
