Product Introduction

云母（mica)是分布广的造岩矿物，钾、铝、镁、铁、锂等层状结构铝硅酸盐的总称。云母普遍存在多型性，其中属单斜晶系者常见，其次为三方晶系，其余少见。云母族矿物中常见的矿物种有黑云母、白云母、金云母、锂云母、绢云母等。云母通常呈假六方或菱形的板状、片状、柱状晶形。颜色随化学成分的变化而异，主要随Fe含量的增多而变深。白云母无色透明或呈浅色；黑云母为黑至深褐、暗绿等色；金云母呈黄色、棕色、绿色或无色；锂云母呈淡紫色、玫瑰红色至灰色。玻璃光泽，解理面上呈珍珠光泽。莫氏硬度一般2～3.5，比重2.7～3.5。平行底面的解理极。白云母是分有很广的造岩矿物之一，在三大岩类中均有产出。泥质岩石在低级区域变质过程中可以形成绢云母，变质程度稍高时，成为白云母。酸性岩浆结晶晚期以及伟晶作用阶段，均有大量白云母生成。由高温至中低温的蚀变作用过程中，也能生成。所谓云英岩化是高温蚀变作用之一，能形成大量白云母。所谓绢云母化作用是中低温蚀变作用之一，能形成大量绢云母。白云母风化破碎成极细的鳞片，既可以成为碎屑沉积物中的碎屑，也可以是泥质岩的矿物成分之一。

白云母和金云母具有良好的电性和不导热、抗酸、抗碱和耐压性能，因而被广泛用来制作电子、电气工业上的材料。云母碎片和粉末用作填料等。锂云母还是提取锂的主要矿物原料。云母矿物由于晶体大，色彩艳丽，很早就被人类利用。中国古籍中对其称谓记载就有：花皮连、天冰、天皮、地金、老刮金、千层纸、元面、云米赤及雄黑等。敦煌莫高窟中唐112窟所用的颜料闪光发亮，经Ｘ射线衍射分析，是白云母经细碎研磨而成。显色效果好。
