ABSTRACT:
A metallothermal reaction mixture consisting of a metal oxide, a metal that is more electronegative than the metal of the metal oxide and, optionally, further additives, the individual components being present in the form of small particles, is prepared in which at least 20% by weight of the metal oxide is present in the form of spherical or at least approximately spherical particles ranging in size from >0 to 3.0 mm. A stabilization and evening out of the reaction is achieved by the invention composition of the reaction mixture.
