ABSTRACT:
A process is disclosed for producing spherical glass particles. The process involves forming a high velocity stream of molten droplets of glass, directing said stream toward a repellent surface, impacting the molten droplets against the surface to form fragmented portions, and cooling the fragmented portions to form a glass powder consisting essentially of particles the major portion of which are glass spheres.
