Potassium Aluminium Fluoride
Encyclopedia
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 dispersion within a charge.
It is also used as an insecticide.

Calcium hydroxide
Calcium hydroxide, traditionally called slaked lime, is an inorganic compound with the chemical formula Ca2. It is a colourless crystal or white powder and is obtained when calcium oxide is mixed, or "slaked" with water. It has many names including hydrated lime, builders lime, slack lime, cal, or...
