Linked from

The 6 pages that link to Flux (metallurgy), each with the reason it gives.

• SolderingRelated: It clears surface films that would prevent solder from wetting the metal.

• FluoriteRelated: Fluorite lowers slag viscosity in metallurgical furnaces.

• SmeltingRelated: Limestone and other fluxes bind ore impurities into slag.

• BoraxRelated: Molten borax dissolves metal oxides and helps protect heated surfaces from further oxidation.

• Copper smeltingRelated: Silica flux binds iron oxides generated from copper sulfide ores.

• SolderRelated: Flux clears surface oxides that would stop molten solder from wetting a joint.
