Mica
Mica a type of phyllosilicate is the name given to a group
of rock-forming minerals characterised by highly perfect basal
cleavage. This means that Mica has a tendency to split along
planes determined by crystal structure, yeilding a great number
of thin, tough, plastic laminae. Among the principal rock-forming
minerals, micas are common in all three major rock varieties--igneous,
sedimentary, and metamorphic.
Mica has an extremely high dielectric strength, low electric
loss, high surface and volume resistivities, excellent thermal
stability and high shear and tensile strengths. It is completely
inert to the action of water, acids, alkalies, oils and solvents.
It is fireproof and noninflammable, unaffected by temperatures
up to 1200 to 1600 degrees F., and is resistant to the oxidizing
action of electrical discharges.
Micas are used in the production of a wide range of products
including; stove windows, boiler gauge packings, as fillers,
as lubricant, absorbant materials, dusting powder, packing
material, wallpaper, roofing paper, paints, in the analysis
of polarised light and are an important source of lithium
and rubidum salts.
Micas excellent electrical, thermal and mechanical stability
leads to its most common use in thermal and electrical applications.
These products are often combined with a range of backing
materials or composites to improve the mechanical strength
or to produce a form that is more easily handled.
