The study of carbonaceous mesophase began with a study in coking process of coals. Many studies about mesophase in heat-treated pitches have been done since those of Brooks and Taylor.
Mesophase has a soluble one and a fusible one in addition to an insoluble and infusible one. These have been cleared up with the physicochemical properties of quinoline-soluble and quinoline-insoluble mesophase, and the heat-treating properties of mesophase by polarized micrograph observation under heating stage.
As an utilization of mesophase now, there are high performance pitch-based carbon fiber and meso-carbon microbeads as a filler of high performance liquid chromatography.
The future utilization of mesophase will depend on the control of mesophase properties.
