    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 (): crystalline folia and compact masses; distinct crystals are not known.The folia have a pronounced pearly luster, owing to the presence of a perfect cleavage parallel to their surfaces: they are flexible but not elastic, and are usually arranged radially in fan

    Pyrophyllite: The mineral pyrophyllite information and

    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. Pyrophyllite is named after the Greek words "pyr" - "fire" and "phyllon" - leaf, regarding its property to exfoliate into fan shapes upon heating.

    Pyrophyllite is a low expansion mineral. The individual particles expand less on heating (and therefore contract less on cooling) than other refractory particles (like silica). Thus, during firing, pyrophyllite particles counter the shrinkage of the plastic components surrounding them (assuming that particles remain whole and undissolved to exert their influence on the surrounding matrix).

    Two different minerals with similar physical properties are talc and pyrophyllite. Their physical properties are nearly identical. Both are very soft: talc is the softest mineral on the Moh's hardness scale at 1, and pyrophyllite is 1 to 2.Both talc and pyrophyllite have perfect cleavage in one direction. This means that these minerals break into thin sheets.
