一、叶蜡石的工业用途 叶蜡石是一种含水的铝硅酸盐矿物,其化学式为Al_2〔Si_4O_(10)〕(OH)_2。细质纯净的叶蜡石具有温润柔软、色泽美观、纹理自然别致、易于刀刻凿琢,是美术工艺品的雕刻材料,如著名的寿山石和青田石。它在工业上可作为耐火材料、坩埚、陶瓷、玻璃纤维、分子筛和水泥原料,并在农药、油漆、橡胶、塑料、造纸、颜料、化妆品等工业有广泛的用途。我国叶蜡石矿消费结构中,陶瓷约占60％,耐火材料和其它窑业约占20～23％,玻璃纤维约占10％。
I. Industrial use of pyrophyllite Pyrophyllite is a hydrous aluminosilicate mineral whose chemical formula is Al_2[Si_4O_(10)](OH)_2. Fine and pure pyrophyllite has a soft, soft color, beautiful color, unique natural texture, and easy carving. It is a carving material for arts and crafts, such as the famous Shoushan Stone and Qingtian Stone. It can be used in industry as a refractory, enamel, ceramic, glass fiber, molecular sieve and cement raw materials, and has a wide range of uses in the pesticide, paint, rubber, plastic, paper, paint, cosmetics and other industries. In China’s pyrophyllite consumption structure, ceramic accounts for about 60%, refractory materials and other kiln industries account for about 20-23%, and glass fiber accounts for about 10%.
