Seven fractions of a coal tar pitch having different molecular weights were carbonized up to 650Β°C under a pressure of 30 MPa in closed and open gold tubes. Carbon yield and microscopic texture of the resultant products were investigated. The graphitizability was evaluated through measurements of in
Carbons were prepared from anthracene, phenanthrene, and their mixtures by first charring in a bomb to 55O"C, followed by coking in a flowing nitrogen stream at 9OO"C, and then heating in helium to 2500Β°C. The cokes and 2500Β°C carbons were characterized using X-ray diffraction, gas adsorotion. densi
