3.Mica's main advantages are insulativity and heat resistance, which
1). If mica's thickness reaches 0.015mm, its average breakdown voltage would be 2.0—5.7kV, puncture strength would be 133-
2). When mica is heated by temperature of 100-600°C, its elasticity
and surface properties will not change.
(1) Used in decorating, paint and coating.
(2) Mica powder is the basic raw material for mica ceramics
(3) It can be used in fire-fighting dry powder, protecting layer of
welding rods, conducting wires and electric cables.
(4)It can be taken as a filler, shelter, lubricating substance,
drawing of patterns in plastics, rubber, asbestos products and
sealing materials. It can also be used as a filler in degreasing
agent of cosmetics, in insulating materials of high-frequent
electric waves and acid-durable products. It can be used as coating
in models of forcasting metal, the brightening material in
aluminium and paint in electroplating bath.
