Abstract
A method is provided for coating magnesium granules with a fluoride-containing salt comprising contacting the granules with at least one fluoride-containing salt selected from the group consisting of alkali and alkaline earth metal fluorides and fluoborates and thereby produce a fluoride-containing coating on the surface of the granules. The coating is characterized in that the oxidation of the magnesium granules is greatly inhibited during the use of the granules as an addition agent to a molten metal bath, for example, when used in the desulfurization of steel.
