What is the use of silicon dioxide powder?

What is Silicon dioxide powder?
Silica is an inorganic compound with the chemical formula of SiO2. Silicon atoms and oxygen atoms are arranged in long-range order to form crystalline silica, and short-range order or long-range disorder arrangement to form amorphous silica.
Silicon dioxide is insoluble in water and acid but soluble in hydrofluoric acid and hot concentrated phosphoric acid and can react with molten alkali. Silicon dioxide is widely used, mainly for making glass, water glass, pottery, enamel, and so on. Pure natural silica crystal is a hard, brittle, insoluble, colorless, and transparent solid which is often used to manufacture optical instruments.
Applications of Silicon dioxide powder
Silicon dioxide is used to make flat glass, glass products, casting sand, glass fiber, ceramic-colored glaze, sandblasting for rust prevention, sand for filtration, flux, refractory materials, and lightweight bubble concrete. Silicon dioxide has a wide range of uses. Crystals, which are scarce in nature, can be used to make important parts, optical instruments, and handicrafts in the electronic industry. Silicon dioxide is an important raw material for manufacturing optical fibers. Generally, pure Shi Ying can be used to make Shi Ying glass. Shi Ying glass has a very small expansion coefficient, which is equivalent to 1/18 of ordinary glass. It can withstand drastic changes in temperature and has good acid resistance (except HF). Therefore, Shi Ying glass is often used to manufacture high-temperature resistant, chemical instruments. Quartz sand is often used as glass raw material and building material.
Silicon dioxide is the raw material for making glass, Shi Ying glass, water glass, optical fiber, important parts of the electronic industry, optical instruments, handicrafts, and refractories, and it is also an important material for scientific research.
When the silicon dioxide crystal is perfect, it is crystal; Silica is agate after gelatinization and dehydration; Silica gel containing water becomes opal after solidification; When the grain size of silica is less than several microns, chalcedony, flint, and secondary quartzite are formed. Mineral resources with very stable physical and chemical properties, crystal belongs to the oxide mineral of the tripartite system, that is, low-temperature Shi Ying (α-Shi Ying), which is the most widely distributed mineral species among Shi Ying minerals. Shi Ying, in a broad sense, also includes high-temperature Shi Ying (β-Shi Ying). Shi Ying Block, also known as silica, is mainly the raw material for producing quartz sand, as well as the raw material for refractories and ferrosilicon firing in Shi Ying.
The food industry is used as an anti-caking agent, defoamer, thickener, filter aid, and clarifier.
Price of Silicon dioxide powder
Silicon dioxide powder particle size and purity will affect the product's price, and the purchase volume can also affect the cost of Silicon dioxide powder. A large amount of large amount will be lower. The price of Silicon dioxide powder can be found on our company's official website.
