Potassium aluminium fluoride (KAlF4) is an inorganic compound.
This compound is used as flux in the smelting of secondary aluminium, to reduce or remove the magnesium content of the melt. 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 rage of products for the metals industry as a fluxing agent within additives to help its despersion within a charge
It is also used as an insecticide. [cite encyclopedia | encyclopedia = AccessScience | url = http://www.accessscience.com/popup.aspx?id=76998&name=def | title = potassium aluminium fluoride]
