伊利石:一种前景广阔的新型粘土矿物材料

伊利石是一种富钾、高铝的层状含水硅酸盐矿物，是近几年来才逐渐受到重视的新型粘土矿物材料。不同品种的伊利石可分别用作陶瓷制品的原材料，造纸用涂布粒等。经改性后的活性伊利石粉可作为橡塑制品的填充料。以优质伊利石为原料制取钾肥，同时还可获得４Ａ沸石、净水剂等多种副产品。伊利石的深层次开发具有广阔的市场前景。

Illite: A New Potential Clay Mineral Material

Illite is a kind of layer silicates contained hydroscopic water, which is charactered by the high content of K and Al. As a new clay mineral material, it has been paid more attention in recently. Different quality illite has different usage, such as the raw materials and burden of ceramics, the coating of paper. The active illite powder after modification can be used as the stuffing of rubber and plastic. The potash fertilizer can be made of the raw materials of good quality illite, during the process, 4A zeolite and water treatment agent can be obtained as by-products. The further exploiting and application of illite is potential in the market.
