Contact SupplierPyrophyllite is a secondary mineral of composition Al2O3 4 SiO2 H2O. Pyrophyllite that we provide to the clients is properly tested and free from impurities. Brightness of pyrophyllite plays a key role in describing the utility and value of Pyrophyllite in different industries. The presence of quartz and colored minerals such as iron-oxide-hydroxide, opaque, chlorite, and miraculous minerals decreases the overall brightness of the material. We efficiently supply Pyrophyllite Powder with 88% to 94% brightness of 200/300/400/500/700 meshes.
Pyrophyllite is a phyllosilicate mineral species belonging to the clay family and composed of aluminum silicate hydroxide :
AlSi2O5OH. Pyrophyllite Powder occur in two more or less distinct varieties, namely, as crystalline folia and as 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-like or spherical groups. This variety, when heated before the blowpipe, exfoliates and swells up to many times its original volume, hence the name pyrophyllite, from the Greek pyros (fire) and phyllos (a leaf), given by R. Hermann in 1829. The color of both varieties is white, pale green, greyish or yellowish; they are very soft (hardness of 1 to 1.5) and are greasy to the touch. The specific gravity is 2.65 - 2.85. The two varieties are thus very similar to talc.
Pyrophyllite Powder :
Pyrophyllite Powder can be collected in fine powdered form that looks like talc but it is unlike talc. We efficiently supply Pyrophyllite Powder to you as per your requirement providing different specifications.
Used For:
Pyrophyllite Powder are easily machined and have excellent thermal stability. Therefore, Pyrophyllite Powder are added to clay to reduce thermal expansion when firing but they also have many other industry uses when combined with other compounds, such as in insecticide and for making bricks. Pyrophyllite is also widely used in high-pressure experiments, both as a gasket material and as a pressure-transmitting medium.
