POTASSIUM ALUMINUM FLUORIDE Usage And Synthesis

Application

Potassium aluminium fluoride (PAF, chemical formula KAlF4) is an inorganic compound. The main environmental issue that arises from using PAF is the production of fluoride gases. Calcium hydroxide is widely used to suppress the fluorides produced but in most cases fails to remove it sufficiently. PAF is also present in a wide range of products for the metals industry as a fluxing agent within additives to help its dispersion within a charge. It is also used as an insecticide.
Potassium Aluminum Fluoride is a commercial purity fused inorganic salt. It has useful properties and is used in a number of industrial applications. The compound is used as salt flux in the smelting of secondary aluminium to maximize metal recovery, to reduce or remove the magnesium content of liquid aluminium alloys and as filler in the manufacture of abrasives. PAF is also present in additives for the metals industry as a fluxing agent to accelarate dispersion after addition.
