According to chemical and mineral composition, pyrophyllite can be divided into wax stone pyrophyllites, diaspore pyrophyllite, kaolinite pyrophyllite, siliceous pyrophyllite, etc. The main mineral of pyrophyllite is pyrophyllite, which accounts for 90%. The others are chalcedony, limonite, and diaspore, which can be used to make ceramics, sculptures, fillers, coatings, and refractory materials. The main mineral of diaspore-based pyrophyllite is pyrophyllite, and the secondary mineral is diaspore, which contains trace amounts of limonite, rutile, etc., which can be used to make refractory materials and glass crucibles. Kaolinite pyrophyllite is the main mineral kaolin, and the secondary mineral is pyrophyllite, which contains trace amounts of limonite, rutile, etc., which can be used to make ceramics and refractory materials. The main mineral of siliceous pyrophyllite is pyrophyllite, the minor minerals are quartz, chalcedony, and the trace minerals are limonite, etc., which can be used to make ceramics, refractory materials, fillers, etc.
