The Oxi-stabilization of Carbon Precursor Using Heat Treated Pitch
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.
Key words: Oxi-stabilization, Swelling, Mesophase pitch, Dimensional stability
