Abstract
Molten pitch is mixed and atomized in an inert gas stream having a temperature less than that of the molten pitch, cooled to the ordinary temperature and separated from the gas stream. Fine powder such as carbon, silica alumina and the like is added to at least one step of the process to improve the fluidity of the thusly obtained fine solid pitch spheres. The pitch spheres are easy to storage, handle and transport as they behave like a fluid.
