Apparatus for making hollow carbon microspheres

摘要

An apparatus for making hollow carbon microspheres starting with hollow microballoons made of a material which can by heating be degraded to a carbon structure having a shape similar to that of the original microballoon. The disclosure teaches specific batch treating steps and apparatus for optimizing the rate of production of the microspheres, while at the same time minimizing degradation, rupture and cracking of the resulting carbon product.
