云母是一种造岩矿物,通常呈假六方或菱形(xing)的板(ban)状(zhuang)、片状(zhuang)、柱状(zhuang)晶(jing)形(xing)。颜色随化(hua)学(xue)成分的变化(hua)而异(yi),主要随Fe含量的增多而变深 。云母(mu)(mu)的特性(xing)(xing)(xing)是绝(jue)缘(yuan)(yuan)、耐高温、有(you)光(guang)泽、物理化(hua)学(xue)性(xing)(xing)(xing)能(neng)稳定,具有(you)良好的隔热性(xing)(xing)(xing)、弹性(xing)(xing)(xing)和韧(ren)性(xing)(xing)(xing),又(you)有(you)被(bei)剥成具有(you)弹性(xing)(xing)(xing)的透明薄片的性(xing)(xing)(xing)能(neng)。在工(gong)业(ye)上用得最多的是白(bai)云母(mu)(mu),其(qi)次为金云母(mu)(mu)。其(qi)的应用于建材行业(ye)、消(xiao)防行业(ye)、灭(mie)火(huo)剂、电焊(han)条(tiao)、塑料(liao)、电绝(jue)缘(yuan)(yuan)、造纸、沥青纸、橡胶、珠光(guang)颜料(liao)等化(hua)工(gong)工(gong)业(ye)。
