Non-Metallic Minerals & Products

Biotite Biotite mainly occurs in metamorphic rocks, granite and other rocks. The color of biotite is from black to brown or green, with glass luster. The shape is plate and column. In recent years, biotite has been widely used in stone paint and other decorative coatings.     The single crystal of wancheng biotite is short columnar and plate-shaped, with a hexagonal cross-section and scaly aggregate. Brown or black. The color becomes darker with the increase of iron content. Other optical and mechanical properties are similar to those of muscovite, with a relative density of 2.7-3.3.

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 2.78-2.88g / cm 3, the hardness is 2- 2.5, and the diameter-thickness ratio is> 50. 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 600 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 1505-2134MPa, the tensile strength is 170-360MPa, the shear strength is 215-302MPa, and the thermal conductivity is 0.419-0.670W. (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. 　       2.

Muscovite 1. Characteristics and uses of mica powder Mica has muscovite, biotite, phlogopite, lepidolite and other types. Muscovite is the most common mica. Mica has high insulation performance, heat resistance, acid resistance, alkali corrosion resistance, and small thermal expansion coefficient. No matter how broken it is, it is in the form of flakes, with good elasticity and toughness. The mica powder has a large diameter-to-thickness ratio, good sliding properties, strong covering performance and strong adhesion. Wancheng Mica powder is widely used in the fields of insulation, heat insulation, paints, coatings, pigments, fire protection, plastics, rubber, ceramics, oil drilling, welding electrodes, cosmetics, aerospace, etc. 2, Mica chemical composition chemical composition SiO 2 Al 2 O 3 Fe 2 O 3 CaO Na 2 O MgO TiO 2 K 2 O H 2 O Content % 45-48 20-33 2-5 0.03-0.05 0.8-1.5 0.69-0.48 0.06-0.65 7-9.8 0.01-0.13 3, The physical properties of Muscovite proportion Refractive index PH value BaiDu Diameter to thickness ratio Moh's hardness Temperature resistance Loss on ignition Moisture 2.87 1.66 7-8 60-80 ＞60 2.75 1000 ℃ 2.8-3% ＜1% 4.
