Pyrophyllite is a micaceous mineral formed as a result of the relatively low grade metamorphism of aluminum-rich rocks. It can also form as a hydrothermal replacement of aluminous minerals such as feldspars. The mineral may be in fine-grained aggregate and is easily mistaken for other phyllosilicates.

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 …

Pyrophyllite, very soft, pale-coloured silicate mineral, hydrated aluminum silicate, Al2(OH)2 Si4O10, 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,

Pyrophyllite is extensively used in the high-pressure synthesis industry as a pressure-transmitting medium because of its outstanding pressure transmission, machinability, and insulation.

Pyrophyllite and talc are both tetrahedra–octahedra–tetrahedra (TOT)-type phyllosilicates, but differences can be found in the stacking mode of the layers and the ion occupation. Fourier transform infrared spectroscopy was used to differentiate between pyrophyllite and talc. In the 400–600 cm−1 region, pyrophyllite exhibits six peaks, …

The chemical analysis of the pyrophyllite sample has been presented in Table 1.The results indicate that the sample was rather low in SiO 2 (59.51%) and rich in Al 2 O 3 (30.43%) in comparison to those of theoretical values (SiO 2 67% and Al 2 O 3 28%). The presence of diaspore as indicated by other studies (XRD analysis and DTA) might have …
