Sericite
1. Main properties: Sericite is a new type of industrial
mineral with a layered structure, which is a subspecies of
muscovite in the mica family with extremely fine scales. The
density is 2.***2.*8g / cm 3, the hardness is **2.5, and the
diameter-thickness ratio is> *0. It can be split into very
thin flakes, with silk luster and smooth feeling, full of
elasticity, flexibility, acid and alkali resistance, strong
electrical insulation, heat resistance (up to **0 o C), and
low coefficient of thermal expansion, and The surface has
strong UV resistance, good abrasion resistance and wear
resistance. The elastic modulus is ********4MPa, the tensile
strength is ******0MPa, the shear strength is ******2MPa, and
the thermal conductivity is 0.****0.**0W. (MK) *1. The main
component is a potassium silicate aluminosilicate mineral,
which is silver-white or grayish-white, in the form of fine
scales. Its molecular formula is (H 2 KAl 3 (SiC4) 3. The
mineral composition is relatively simple and the content of
toxic elements is extremely low, No radioactive elements can
be used as green materials. Wancheng is an mica
powder manufacturer.
