Abstract

On the spontaneous ignition of NC, the effect of water and oxygen and that of nitrogen dioxide and oxygen were investigated by observing the thermal behavior and structural change. As the result, it was observed that hardly any exothermic degradation took place only by nitrogen dioxide nor water; hardly any exothermic degradation took place in atmospheres without oxygen. From this, it was suggested that exothermic degradation was due to oxygen and it was promoted by nitrogen dioxide and water. The results indicated that auto-oxidation caused by atmospheric oxygen could explain the spontaneous ignition mechanism of NC.
