1, Properties: Yunfen is a nonmetallic mineral with various components, mainly containing SiO2 and Al2O3. Mica powder is a good additive, which has the characteristics of elasticity, toughness, insulation, high temperature resistance, acid and alkali resistance, corrosion resistance and strong adhesion.

2. Composition: The main component of cloud powder is SiO2, with a content of about 49% and Al2O3 content of about 30%. The components of mica powder are more diverse, including Fe2O3, MgO, CaO, Na2O, K2O, etc. in addition to the main components of silica and Al2O3.

3. Uses: Cloud powder is widely used in electrical appliances, welding electrodes, rubber, plastics, paper, paints, coatings, pigments, ceramics, cosmetics, new building materials and other industries. Mica powder is more widely used, not only in the above industries, but also in the manufacture of cosmetics, medicines, chemical reagents, metallurgy, food, radioactive substances and so on.
