Mica process characteristics and main uses


    1, process characteristics


    (1) Physical properties. The physical properties of mica mainly depend on the size of mica crystals, stripping properties determined by cleavage and hardness, and the color transparency and elasticity of mica. Industrial mica is mostly plate-like or book-like crystals, with crystal sizes ranging from a few millimeters to tens of centimeters in thickness, and generally has a direct use value as long as the effective crystal area is greater than or equal to 4 cm2. Of course, the larger the crystal area, the higher the value. The stripping performance of mica is determined by the cleavage and hardness of mica. The unique crystal structure of mica gives it an extremely complete set of bottom cleaving, which has become an important feature of industrial mica technology for stripping. In theory, muscovite can be stripped to about 10, and phlogopite can be stripped to about 5
