... proceeds further, a large number of optically anisotropic mesophase spherules appears in petroleum pitch. Those spherules can be separated from the pitch as a quinoline insoluble matter, the spherules thus separated being called meso-carbon microbeads. The microbeads can be used as a binder pitch improver...
