Pyrophyllite Powder is a phyllosilicate mineral species belonging to the clay family and composed of aluminum silicate hydroxide. Pyrophyllite is a hydrous aluminum silicate with a structure similar to talc. Such properties as chemical inertness, high dielectric strength, high melting point, and low electrical conductivity make it useful for ceramic and refractory applications. It resembles closely with talc in many physical and optical properties but differs chemically. The offered Pyrophyllite Powder is very effective and useful.
