Abstract
For the purpose of preparing compact single-phase gallium phosphide according to the horizontal Bridgman process, a melting vessel having a circular cross-section made of a non-conductive inorganic material is used. As a result of direct inductive coupling of the gallium melt it makes it possible to generate the reaction temperature required for the reaction of 1250 DEG in a narrow zone. The diameter of the melting vessel (1) should be only slightly smaller than the diameter of the reaction vial (5) and this should be only slightly smaller than the diameter of the induction coil (6). <IMAGE>
