Calcium fluoride is an inorganic compound that is colorless crystal or white powder. Insoluble in water, slightly soluble in inorganic acid, react with hot concentrated sulfuric acid to produce hydrofluoric acid. In general, calcium fluoride is prepared by the interaction of calcium carbonate with hydrofluoric acid or by repeated treatment of fluorite powder with concentrated hydrochloric acid or hydrofluoric acid.Read more -

Its pure kaolin is white, delicate, soft soil, with good plasticity and fire resistance and other physical and chemical properties. Its mineral composition is mainly composed of kaolinite, Eloite, hydromica, illite, montmorillonite, quartz, feldspar and other minerals. Kaolin is widely used, mainly for paper making, ceramics and refractory materials, followed by paint, rubber fillers, enamel glaze and white cement raw materials, a small amount of plastic, paint, pigments, grinding wheels, pencils, daily cosmetics, soap, pesticides, medicine, textile, petroleum, chemical, building materials, national defense and other industrial sectors.Read more -
Perlite is widely used in horticulture and agriculture, often used to improve soil structure, increase soil ventilation and water retention, help the growth of flower roots, suitable for plants that like dry and aerated environment, such as cacti, succulents, orchids, etc., not suitable for plants that like moist environment, such as aloe vera, bromeliads, etc.Read more -
Volcanic stone (volcanic rock or pumice) is a kind of glassy lava with dense pores formed by the rapid expansion of internal gas due to the sharp reduction of pressure after the sudden cooling of magma during the volcanic eruption. The pore volume accounts for more than 50% of the rock volume. It is called pumice because of its many pores, light weight and ability to float on the surface of the water. It is characterized by high strength, heat preservation, heat insulation, sound absorption, fire protection, acid and alkali resistance, corrosion resistance, and no pollution, no radioactivity.Read more -
Uses of kaolin Pure kaolin has high whiteness, soft quality, easy to disperse suspended in water, good plasticity and high cohesiveness, excellent electrical insulation properties; It has good acid solubility, low cation exchange capacity, good fire resistance and other physical and chemical properties.Read more -
Industrial alumina is prepared from bauxite (AlzOs-3H2O) and diaspore, and A1203, which requires high purity, is generally prepared by chemical methods. A1203 has a lot of homogenous crystals, there are more than 10 known, there are mainly 3 crystal types, namely A-Alzos, B-AlzOs, Y-AlzOs. Among them, different structures and properties are different, and it is almost completely converted into a-AlzO3 at high temperatures above 1300℃.Read more -
