Product Description
Quartz
Silica is a white powder solid, non-toxic, odorless. It is a transparent or translucent tiny particle with a multi-microporous structure, high specific surface area, high mechanical strength, and high silica content. Good thermal stability, good acid resistance (except hydrofluoric acid). Soluble in caustic soda. It has a strong adsorption effect on water vapor and other gases and solvents. Silicon dioxide (SiO2) is the most abundant of all minerals. Silica, which occurs in nature, is called silica and makes up about 12% of the Earth's crust by weight. The melting point of quartz is 1 610℃. Except for fluorine, hydrogen fluoride and hydrofluoric acid, it does not react with halogens, hydrogen halides and inorganic acids. But soluble in hot concentrated lye and molten alkali or sodium carbonate. There are three different crystal types of silica, quartz, squame-quartz and cristobalite, quartz is the most stable at room temperature, and the other two are stable at high temperatures, because they are very slow to convert into quartz, so they also exist at room temperature.

Product application
1, silica: mainly used as lubricant, anti-stick agent, flow aid. 2, food and beverage silica: flow additives, anti-caking performance. 3, rubber silica: eliminate internal tension, delamination and cracking phenomenon. 4, paint, coating silica: control rheology, anti-light, anti-hanging, anti-ultraviolet, anti-settlement, improve corrosion resistance. 5, papermaking silica: ink absorption speed is fast, high whiteness, printing image is clear and bright. 6, mold silica: with excellent dispersion, compatibility, high transparency, high whiteness. 7, also produces other silica for oil, edible oil decolorizing agent, toothpaste grinding agent, leather special matting agent, etc.
