Pyrophyllite is a kind of hydrous aluminum silicate mineral, with
melting point of 1,700℃, white, platy radial aggregate. It is of
gloss, toughness, chemical stability, low thermal expansion, low
thermal conductivity, low electrical conductivity, high insulating
ability, high melting point and favorable corrosion resistance.
Pyrophyllite Chemical Composition: Al2O3≥25~30%, SiO2≤55~70%, Fe2O3≤1.0%. Whiteness≥85%
I. Due to high melting point and low thermal expansion, Pyrophyllite is used to reduce sintering temperature, decrease shrinkage and
cracking, resist thermal expansion or used as filler in ceramics
industry, such as ceramic tile, sanitary ware, dinnerware and
porcelain electrical supplies.
II. Due to high melting point, Pyrophyllite is used in refractory materials, or used to add to glass fiber raw
material in the form of alumina and monox to promote flowing, or
used as filler in insulating firebrick, refractory material of
furnace and kiln, or mold wash.
III. Due to chemical stability, acid and alkali corrosion
resistance, high insulating quality, whiteness, absorbing property
and flowability, it is used as carrier or filler in insecticide,
specialized fertilizer, paint, rubber, paper making, dyestuff,
pharmacy, sugar processing, cosmetics and plastic products.
