ABSTRACT:
The invention relates to magnesium-containing mixtures, in the form of granules of a particular shape, made by the introduction of a salt to liquid metal at a temperature of 670.degree.-720.degree.C, heated to a temperature of 670.degree.-730.degree.C, composed of metal chlorides and fluorides not reducible by magnesium, taken separately or in combination, and having an initial crystallization temperature below that of the granulated metal, and a density at the temperature of 670.degree.-730.degree.C equal to 0.95-1.2 of the density of the metal. The molten mixture is atomized by centrifugal force with subsequent cooling of the thus produced discrete particles by air flow. The mixture obtained in producing granules of magnesium or its alloys comprises in weight per cent: 65-97 of granulated magnesium, 0.3-16 of magnesium and alkali metal chlorides, 0.1-10 of one of the fluorides, up to 3 of alkaline-earth metal chlorides, and up to 6 of magnesium oxide. The above mixture can also comprise in weight per cent: 60-97 of granulated magnesium alloy, 0.3-16 of magnesium and alkali metal chlorides, 0.1-10 of one of the fluorides, 0.3-10 of alkaline-earth metal chlorides, and not over 5.0 of magnesium oxide.
