High Purity Cryolite Na3alf6 for Glass Industry

Product Description

Product Application
It's mainly used as a flux in aluminum smelting by fused-salt electrolysis; also an opalizer in the manufacture of enamel; an opacifier and auxiliary solvent of glass and enamel; an insecticide of crops; a flux in aluminum alloy casting; and in the production of ferrous alloy and effervescing steel; as well as a wear-resistant filler for resin and rubber-boned abrasive wheels.

Especially in ceramics, cryolite has many usages:
First, as the additive for glaze: Cryolite has high melting points and fire resistance. Adding to the glaze can increase the glaze's melting degree, and make the glaze smoother. Meanwhile, cryolite can improve the impact and abrasion resistance of the glaze.
Second, as a ceramic color, cryolite can play a colored role in ceramics, especially for warm colors such as red, orange, and yellow.
As an enhanced agent of ceramics: cryolite can improve the strength, toughness, and stability of the ceramics, and make the ceramics stronger.
Also as an additive for the filler: cryolite can be used as an excellent filler to improve the hardness and density of ceramic products.

Product Features
Cryolite as one of the ceramic raw materials, provides many advantages for producing ceramics.
Stable property: The composition of MgO and silicate makes cryolite have good chemical stability. Therefore, ceramic products made of cryolite as ceramic raw materials have high corrosion resistance and chemical stability and can remain intact in a variety of environments for a long time.
High hardness: The hardness of cryolite can reach 6.5-7 Mohs. So when making ceramics products using cryolite, the products' surface will be harder, won't be easy to scratch and wear, not easily lose luster, keep beautiful.
Antioxidant and high-temperature resistance: Cryolite is not easy to oxidize at high temperatures, can resist thermal shock, and the crystals in its products will not change too much at high temperatures. Ceramic products made of cryolite as ceramic raw materials can be used for a long time, with good high-temperature resistance and oxidation resistance, and it is not easy to crack or deform even in high-temperature environments.
