(Na₃AlF₆). Synthetic cryolite is a white crystalline powder manufactured from hydrofluoric acid, sodium carbonate, and aluminium. Synthetic cryolite is used chiefly as a flux in the electrolytic production of aluminum as it effectively lowers down the melting point of alumina. It is used in the glass and enamel industries, in bonded abrasives as a filler, in making salts of sodium and aluminum and porcelaneous glass and in the manufacture of insecticides. Cryolite is a relatively safe fruit and vegetable insecticide. The fluoride ion inhibits many enzymes that contain iron, calcium, and magnesium.

sodium cryolite is a white crystalline powder or a sandy-size granularity, and a pinkish crystalline powder or a sandy-size granularity as well. Sp.gr.2.95—3.05g/cm3, melting point about 1025°C, specific heat 1.056j/g°C at 18—100°C. It’s slightly soluble in water, but insoluble in anhydrous hydrogen fluoride. The content of its crystal water will be decreased while the increasing of the molecular ratio, therefore its loss on ignition will be also decreased while the increasing of the molecular ratio. After the paste of synthetic cryolite with different molecular ratio dehydrates, the loss on ignition at 800°C will appear 10.34%, 6.22% and 2.56% when the molecular ratio reaches 1.74, 2.14 and 2.63 reactively.

Features:

Sodium cryolite mainly used as a flux in the 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.

sodium cryolite is used as flux in aluminum smelting, cropper insecticide, flux and whiting agent of enamel glaze. It is also used in the manufacture of milky white glass, aluminum alloy and boiling steel. Its used as ingredient of grinding wheel.

Sodium Cryolite is a white crystalline powder, also known by other names such as Sodium Aluminum Fluoride, Sodium Fluoroaluminate, and Trisodium Hexafluoroaluminate. It is primarily manufactured from hydrofluoric acid, sodium carbonate, and aluminum. Sodium Cryolite plays a crucial role in various industrial applications, particularly in the production of aluminum. It is an essential flux in the electrolytic production of aluminum and is also widely used in glass and enamel industries, abrasives manufacturing, and as an insecticide.
