Product Description

 

Characteristics of pyrophyllite

The characteristics of pyrophyllite are similar to talc in appearance, and many physical properties are similar to talc. Natural whiteness 25°~90°, loss on ignition 4%~6%, refractoriness up to 1690°C, hardness of Mohs 1~2, density (specific gravity) 2.8~2.9


The use of pyrophyllite
1. Used as a refractory

Pyrophyllite contains silicon dioxide and aluminum oxide. It does not melt when heated. It is a raw material for manufacturing aluminum silicate refractory materials. Its essential requirements limit iron oxide content. Generally, aluminum oxide (Al2O3) ≥ 24%, (Fe2O3) 1670ºC.

2. Used as ceramic raw material
Pyrophyllite can be used for daily ceramics and architectural ceramics.
3. Make crafts and decorative materials
4. Used in artificial diamond industry
5. Make glass fiber
6. Do stuffing
7. Other uses:

(1) Directly processed into electrical insulation parts and high insulation devices;
(2) The wax powder can be used as a blend of pesticides and pesticides;
(3) The main ingredients of artificial powder sieve and white cement;
(4) Paint for enamelware;
(5) Do anti-sticking release agent for other industries.
