MICA INFORMATION
Mica has an unusual particle shape. It is wide and long but very thin. Also it is very flexible, withstands high temperatures, and can have an attractive appearance.
MICA USES
Mica is used in paints, sealants, plastics, cosmetics, artificial stone, high tech applications, and other manufacturing.

TYPES AND CHEMICAL COMPOSITION OF MICAS
There are three naturally occurring types of Mica and one synthetic grade of
mica commercially available. Micas have high aspect ratios, are flexible and
compressible. They are used in paints, sealants, plastics, cosmetics, artificial stone and other manufacturing.
PHLOGOPITE MICA:
KMg3(Si3AlO10)(OH,F)2
Magnesium substituted mica
Golden or tan color
Stable at high temperatures
Available as powder, flakes and sheets
BIOTITE MICA:
K(Mg,Fe)3(Si3AlO10)(OH,F)2
