Sericite is a new type of industrial mineral with a layered structure, belonging to the mica family and being a sub-species of white mica characterized by extremely thin scales. Its density ranges from 2.78 to 2.88 g/cm³.³, Hardness 2-2.5, diameter-to-thickness ratio >50. Can be split into extremely thin sheets, with a silk-like luster and a smooth feel, featuring elasticity, bendability, resistance to acids and alkalis, strong electrical insulation, and heat resistance (up to 600^oC) Features a lower coefficient of thermal expansion, with a strong resistance to UV rays, excellent wear and abrasion resistance. Elastic modulus ranges from 1505 to 2134 MPa, tensile strength from 170 to 360 MPa, and shear strength from 215 to 302 MPa. Thermal conductivity is 0.419-0.670 W/(m·K).^-1. The main component is a potassium-containing aluminum silicate mineral, which is actually silver-white or grayish-white in color, with a fine scale-like appearance. Its molecular formula is (H₂KAl₃(SiC4)₃The mineral composition is relatively simple, with extremely low levels of toxic elements and no radioactive elements, making it suitable as an environmentally friendly material.
