Synthesis of mica
Description：
Synthetic mica chips
Are manufactured from some chemical materials by means of melting
at high temperature and then crystallizing.The single crystals of
synthetic Fluorophlogopite , KMg3(AlSi3 O10)F2,belongs to monoclinal crystal , layer-type silicate.
Synthetic mica chips
Comparing with nature mica ,synthetic Fluorophlogopite has more
heat endurance (up to 1200℃) than other nature mica.Being the
excellent
insulation material it is stable towards acids,alkalis and poison
gases.With inner-thermo method,the chip contents is above 95%, it
can be made for mica paper,mica lamination sheet,mica ceramics ,
mica tape and so on . It is widely used as electrical insulation in
electrical devices ,or electrical home appliances ,or a component
part of motor ,coil , or air and space material,and others industry
and high technical areas.

Application：The widest usage in the world of industry is the white
mica, the second is the golden mica. The largest applications are
in acid-resistant, insulated, antacid, antalkali, anta processing
and shelling as materials in producing electric equipment and
insulated materials; another user is in producing steam boiler
body, window and machinery parts.
Mica scraps and powders can be used as the materials in processing
mica papersInstead of mica clips in many cheaper and averaged
deep-sizes insulated materials. Moreover, the scrap mica is
wide-used in making oilpraint 、rubber、plastics etc. industrials
lines as filling and construction materials.
Physical characteristic:
The mica is a kind of layered silicate mineral including water .For
the mica, there are many types. The mica powder is uniquely in acid
proof, basify proof, chemical stability performance, and it is also
good in insulation and the thermal stability, none -burning, and
antisepsis
The natural mica powder widely applies in insulation, adiabatic,
painting, plastic, rubber, ceramics, petroleum, well drilling,
welding rod, cosmetics, astronavigation and so on. The superfine
mica powder can be made as function padding in the plastic,
coating, painting, rubber and etc. it may enhance the mechanical
strength, toughness enhancement, strong attachment, anti- aging and
anti-corrosive and so on. Besides the extremely high electric
insulation, anti-acid and alkali corrosiveness, heat-resisting
sound-insulated, and the small thermal-expansion coefficient, it
also takes the lead to promote the body two surfaces
