Aluminium Fluoride
AlF₃
Aluminium fluoride (AlF₃) is a white free-flowing powder, mainly used as an additive for the production of primary aluminium metal.
The addition of aluminum fluoride to the raw materials used in the aluminum smelting process reduces the temperature and improves the conductivity of the molten bath, reducing the electric power consumption.
Noralf produces high-density aluminium fluoride through the “dry process”, according to the following reactions:
1. dry acid grade fluorspar (CaF2) reacts with sulphuric acid (H2SO4) in externally heated rotary kilns, generating gaseous hydrogen fluoride (HF) and calcium sulphate (CaSO4);
2. the gaseous HF reacts with dry aluminium hydrate Al(OH)3 in fluidised bed reactors to produce high density aluminium fluoride.
Aluminium fluoride is available in bulk (silo trucks or bulk vessels) or bagged in 1 MT big bags, 1.5 MT big bags.
