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.
