In metallurgy, a flux is any substance introduced in the smelting of ores to promote fluidity and to remove objectionable impurities in the form of slag. Examples are limestone (used in smelting iron ores), silica, dolomite, lime, borax, and fluorite. In soldering, a flux is used to remove oxide films, promote wetting, and prevent reoxidation of the surfaces during heating. Examples are rosin, or an aqueous solution of zinc chloride and ammonium chloride.
