● 理化性质 化学组成为KM(AlSi3O10)(OH)2（其中M 为 Al, Fe或Mg）的一系列矿物粉体的总称。属于单斜晶体、典型的平面结构。比重2.8，莫氏硬度2.3。产品分两类：干法粗磨和湿法超细，干法工艺生产的悬浮性差、易沉淀、湿法生产的悬浮性好、附着力强。
● 用途 特别适用于电子工业和装饰业， 并广泛应用于油漆、油墨、涂料、塑料、橡胶、陶瓷、玻璃、电子、化妆品等领域。
● 包装 25Kg/包，纸塑复合袋，也可根据客户要求包装。
● Properties Chemical formation KM(AlSi3O10)(OH)2, and M may be Al, Fe, Mg. Wet-processed mica has low suspension, easy to be precipitated, dry-processed mica has good suspension and strong adhesion.
● Application In paints, insulating material of electrical material, engineering plastic PVC.
● Package In plastic woven bag with net weight of 25kg each, or as per requirements.
