Preparation and Growth Characteristics of Mesocarbon Microbeads

Abstract

Mesocarbon microbeads (MCMBs) have been synthesized from coal tar pitch. Scanning electron microscopy (SEM) and laser particle size analyzer were used to evaluate the structure and partical size. The effect of process parameters on the growth and morphologies of MCMBs was investigated. The results show that the optimum temperature range is 410-430 °C and the growth time has a suitable range. The diameter and yield of MCMBs will increase and the spherical degree does not change with the extension of time.
