Patent Images
1. THE PROCESS OF PRODUCING SPHERICAL METALLIC PARTICLES FROM IRREGULAR SHAPED METALLIC PARTICLES WHICH COMPRISES UNIFORMLY DISPERSING SAID IRREGULAR PARTICLES IN A LOOSELY PACKED MATRIX MATERIAL WHICH IS CHEMICALY UNREACTIVE WITH THE METAL PARTICLES AND HAS A SOFTENING TEMPERATURE ABOVE THE MELTING POINT OF SAID METALLIC PARTICLES TO PROVIDE A SUSPENSION OF SAID IRREGULAR METALLIC PARTICLES IN THE MATRIX MATERIAL HEATING SAID SUSPENSION TO A TEMPERATURE BELOW THE MELTING POINT OF SAID PARTICLES SAID TEMPERATURE BEING SUFFICIENT TO SPHERIFY THE IRREGULAR METALLIC PARTICLES IN THE ABSENCE OF COMBUSTION OF SAID MATRIC MATERIAL, COOLING SAID SUSPENSIJO, AND SEPARATING THE SPHERIFIED METALLIC PARTICLES FROM THE MATRIX MATERIAL.
