Pyrophyllite - Wikipedia
Pyrophyllite is a phyllosilicate mineral composed of aluminium silicate hydroxide: Al 2 Si 4 O 10 (OH) 2. It occurs in two forms (habits): crystalline folia and compact masses; distinct crystals are not known.
Pyrophyllite | Uses, Properties & Structure | Britannica
pyrophyllite, very soft, pale-coloured silicate mineral, hydrated aluminum silicate, Al 2 (OH) 2 Si 4 O 1 0, that is the main constituent of some schistose rocks. The most extensive commercial deposits are in North Carolina, but pyrophyllite is also mined in California, China, India, Thailand, Japan, Korea, and South Africa.
The Mineral pyrophyllite - The Mineral and Gemstone Kingdom
The Mineral pyrophyllite. Pyrophyllite is isomorphous with the common mineral Talc, but has aluminum in place of the magnesium. It is very similar to Talc, with very similar properties and habits. However, it has distinct radiating crystal aggregates which easily identify it.
