Hydrofluoric Acid 49% Solution is a colorless liquid. Hydrofluoric Acid, 49% Solution, contains 49% Hydrofluoric Acid mixed with a balanced quantity of Water. It can be used for the electronic industry to perform cleaning of silicon wafers and etching of semiconductors, as these delicate applications require ultra-purified solvents. Hydrofluoric acid is used in a variety of over-the-counter products such as toilet bowl cleaners, concrete cleaners, and metal polishes. However, the uses for industrial applications are far more numerous. hydrofluoric acid is used for quartz purification, glass etching, refrigerant manufacturing, pharmaceuticals, high octane gasoline, aluminum production, plastics, electrical components, and fluorescent light bulbs.

Colorless or white crystal. Insoluble in water, insoluble in acids and bases. It is very stable and can be hydrolyzed when heated. Mainly used in aluminum smelting. It can be prepared by the action of aluminum trichloride and hydrofluoric acid and ammonia. It is mainly used to adjust the molecular ratio in aluminum electrolyzing bath as a flux. The anhydrous AlF3 supplied by our company an reduce environmental pollution;improve the production yield of aluminum smelters, and lower its electrolytic cost.
Physical And Chemical Properties The pH of a 5% aqueous solution of Ammonium Bifluoride is 3.5. In aqueous solution it releases 0.35 pounds of hydrofluoric acid per pound of Ammonium Bifluoride. In strong acid solutions, Ammonium Bifluoride releases 0.70 pounds of hydrofluoric acid per pound. Since the product absorbs heat when aqueous solutions are prepared, it is often advisable to use warm water. Additional properties are listed below.
