Aluminium granules and aluminium powder are widely used in metallurgy industry as reducing agent for production of ferro-alloys (aluminothermic procedure), since aluminium tends to be readily oxidized, releasing the huge amount of thermal energy. Additional applications of aluminium granules and aluminium powder are: as deoxidant for specialty steels and ladle treatment in steel production, reducing agent for slag treatment, manufacture of chromium metal, aluminothermic welding mixtures, sewage cleansing reactant, filler for casting form-molding, etc.
