Abstract
By heat treating coal tar pitch between 450∼500$^{\circ}C$, mesophase pitch could be obtained. Subsequently, this pitch was oxi-stabilized between 160∼240$^{\circ}C$ in air for the purpose of reducing swelling and distortion. The mechanism of stabilization was analysed using the thermo-gravity and FT-IR. To investigate the effect of oxi-stabilization, the shore hardness and bending stress were measured with carbonized green body which was made from oxi-stabilized coal tar pitch.
