Description: When found in nature, fluorspar is known by the mineral name fluorite. Fluorspar is calcium fluoride (CaF 2).Metallurgical grade fluorspar (60–85% CaF 2), is traditionally used as a flux to lower the melting point of raw materials in steel production to facilitate the removal of impurities, and in the production of aluminum.. Ceramic grade fluorspar (85–95% CaF 2) is used in

Some would argue that a limit of 6.0 hours is insufficient to prevent corrosion of some fuel system components such as metal fuel tanks used in some vehicles. Tests with a B5 made from a B100 having an oxidation stability of 6.3 hours and that fully meet the other limits of EN 14214 produced significant corrosion in fuel tank tests with lead-tin alloy coated and electrolytic zinc-coated steel.
