Phyllite properties are essential when it comes to identification of rocks. The study of properties of Phyllite rock is done by Mineralogists to determine the identity of rock. Some of the properties of Phyllite include: Hardness, Color, Fracture, Luster, Compressive Strength etc. Phyllite is Medium to Fine Coarse Grained. As compared to other rocks, Phyllite is more porous and its density is 2.18-3.3 g/cm3. Get to know more about physical properties of Phyllite and thermal properties of Phyllite.
