Pyrophyllite powder is a silicate composed of silicon dioxide and aluminum oxide. It has a high melting point, does not shrink at high temperatures, has stable chemical properties, is non-toxic, resistant to corrosion, has no expansion and plasticity in water, and is good It has the characteristics of low sintering temperature, low electrical conductivity, low expansion coefficient and so on. Pyrophyllite is one of the important production raw materials for functional ceramics (super-hard ceramics, ultra-high-voltage electric porcelain), new green refractory materials, high-performance glass fibers, super-hard materials (man-made diamonds), etc. It is an important new energy source (wind power, fan Blade) materials and new functional materials. It is also suitable for plastics and related modifications, coatings and infrared blocking materials, rubber, inks, sealants, refractory materials, and flame retardant materials, personal care, agricultural fertilizers, papermaking, and other industries.
