Abstract:By means of“heating stirring polymerization”, pitch mesophase was prepared from petroleum pitch and coal tar pitch. Through the following processing, such as grinding, activating adjustment, moulding and sintering, a new type of binderless carbon material with self-sintering function was made from the pitch mesophase. The flexural strength of the material is higher than 50MPa. TheRvalue of the mesophase powder has significant influence on the final properties of the material, and the suitableRvalue is 0.2~0.3.
Key words: pitch mesophase self sintering high strength carbon material
