Pyrophyllite CG1
Pyrophyllite is a phyllosilicate mineral composed of aluminum silicate hydroxide. It is typically found in metamorphic rocks and is characterized by its fine-grained, plat or foliated structure. Here are some key characteristics and common uses of pyrophyllite:
1. Chemical Composition:
Pyrophyllite has the chemical formula Al2Si4O10(OH)2, representing a complex structure of aluminium, silicon, and oxygen.
2. Physical Properties:
Color: Typically white, green, grey, brown, or yellow.
Hardness: Relatively soft, with a hardness of 1 to 1.5 on the Mohs scale.
Texture: Smooth and soapy to the touch.
