ABSTRACT:
Briquets having an overall bulk density in the range of 1.4 to 2.2 g/cm.sup.3, squeeze strength at room temperature in the range of 30 to 230 kg/cm.sup.2, an overall porosity in the range of 35 to 55% and a refractoriness in the range of Pyrometric Cone No. 15 to No. 31 and used as the raw material for high-temperature pyrolitic reduction of magnesium are disclosed. Also disclosed is a method for the production of magnesium by high-temperature pyrolitic reduction, characterized by allowing said briquets as the material for high-temperature reduction to be retained undisintegrated in a floating state on the surface of the slag formed in the electric furnace until vaporization of magnesium from said briquets ceases.
