Sodium Cryolite

We are a well known Manufacturer, Supplier and Exporter of Sodium Cryolite from Sarigam, Gujarat. Sodium Cryolite offered by us is majorly used as flux in aluminum smelting, but it also plays a role in manufacture of enamel and glass and as an insecticide ingredient. To make sure that customers receive a quality product, we package Sodium Cryolite within high grade materials. Clients can order bulk quantities of Sodium Cryolite at reasonable prices.
Details :

• Synthetic Cryolite (Na₃AlF₆) is a white crystalline powder manufactured from hydrofluoric acid, sodium carbonate, and aluminium. The pinkish crystalline powder has sandy-size granularity.
• 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.

(Sp.gr.2.95—3.01g/cm³; melting point about 1000^oC; specific heat 1.056j/g^oC at 18—100^oC;)

• It is 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 800Â^oC will appear 10.34%, 6.22% and 2.56% when the molecular ratio reaches 1.74, 2.14 and 2.63 reactively.

Features :

• Majorly as a flux in the aluminum smelting by fused-salt electrolysis
• opalizer in the manufacture of enamel
• Opacifier and auxiliary solvent of glass and enamel
• Insecticide of crops
• Flux in aluminum alloy casting
• Production of ferrous alloy and effervescing steel; as well as wear-resistant filler for resin and rubber-boned abrasive wheels
