Potassium Cryolite as degassing agent and flux in aluminum alloy fabrication
Application:
Potassium Aluminum Fluoride is a commercial grade fused solid, inorganic salt. The material serves as an alternative to conventional fluoride salts for a variety of applications.The fluoroaluminate is formed by reacting anhydrous hydrofluoric acid with aluminum hydroxide, then reacting with potassium hydroxide at a high temperature, filtering, drying, melting, and crushing. It can also be prepared by reacting aluminum fluoride, ammonium fluoride and potassium chloride.

Physical properties
| 1 | Aluminum fluoride is available as white powder or crystal with density of 3.00g/cm3, melting point is 1040°C, boiling point is 1272°C. |
| 2 | It is slightly soluble in water, hardly soluble in acid and alkali solution, insoluble in most organic solvents, also insoluble in hydrofluoric acid and liquefied hydrogen fluoride. |
| 3 | The property of anhydrous aluminum fluoride is very stable. |
| 4 | It doesn’t react with liquid ammonia or concentrated sulfuric acid by heating to fuming and doesn’t changeable when co-melted with potassium hydroxide. |
| 5 | It is not reduced by hydrogen and doesn’t decompose through heating but it may sublime. |
| 6 | It can be hydrolyzed partly to hydrogen fluoride and aluminum oxide in the vapour of 300-400°C. |
Application
| 1 | Aluminum fluoride is used as auxiliary ingredient of electrolyte during the production of electrolytic aluminum to decrease the melting point and increase the conductivity of electrolyte. |
| 2 | it is a flux for non-ferrous metal, as a zymotic inhibitor in the alcohol and essential oil production and as a fusing assistant for ceramic, enamel and the component of glaze. |
