一、花崗■晶岩白云母礦床的礦物和地質特征白云母的工業用途西方國家約在19世紀以前,就把这种透明的、有彈性的、可以劈裂成薄片的白云母,作为建筑材料或作教堂里的玻璃用;解放前,我国產云母的边区居民,也把大片的白云母用以裱糊灯籠。由于科学技术的進步,証明白云母具有極高的抗电强度和其他物理化学性能,因而广泛地应用到电气 Mineralogy and Geological Characteristics of Granite ■ Geiticite Muscovite Deposits Industrial Use of Muscovite The Western countries introduced muscovite muscovite, which can be cleaved into thin sheets, approximately as early as the 19th century Materials or used as glass in the church; before liberation, mica in China’s border region residents, but also large tracts of muscovites used to paper lanterns. As a result of advances in science and technology, it is proved that muscovite has a very high electric strength and other physicochemical properties and is therefore widely used in electrical
