The oxidized fiber of coal-tar based mesophase pitch showed the maximum weight gain at a particular oxidation temperature according to the heating rate to the temperature as the balance ofoxygen uptake and decomposition of oxygen functional groups. The graphitized fiber showed the maximum tensile pr

It is definite that stabilization conditions such as stabilization temperature, time, and heating rate, as well as partial pressure of oxygen, are very influential in the formation of a skin-core structure in carbonized fibers about 10 urn in diameter, defining the thickness of the skin as well as t
It is shown that the mesomorphic state of a typical pitch (Ashland 240), immediately prior to coking, can be extruded to produce a specified coke morphology. The rheology of the extrudate, the degree of preferred orientation induced and the nature of the cokes derived therefrom vary enormously depe
