Product Name:Pyrophyllite
English Name:Pyrophyllite
CAS No.:12269-78-2
Aliases:Pyrophyllite powder, Soapstone
Molecular Formula:Al2Si4O10(OH)2
Physical Properties:Pyrophyllite is a hydrous aluminum silicate mineral with the theoretical chemical formula Al2Si4O10(OH)2 and a molecular weight of approximately 360.31. It has a Mohs hardness of 1-2, density of 2.65-2.90 g/cm³, layered structure, soft texture, and a greasy feel. It exhibits excellent heat resistance with a melting point of about 1700°C, is chemically stable, insoluble in water, and resistant to both acids and alkalis.
Uses:Pyrophyllite is mainly used in ceramics, refractory materials, fiberglass, rubber, and plastics industries as a filler or raw material. In the ceramic industry, it improves the whiteness and strength of the body; in refractories, it serves as a raw material for high-alumina refractory products.
Technical Specifications:
Purity ≥ 99%
Whiteness ≥ 90%
Alumina content ≥ 28%, silica content ≤ 66%
Residue on 200-mesh sieve ≤ 5%
Moisture content ≤ 0.5%
