摘要
采用 X射线衍射 (XRD)和扫描电镜 (SEM)对煤油、汽油、柴油和环已烷四种液烃前驱体的热解碳分析表明 :热解碳的石墨化能力依次为煤油 >柴油 >汽油 >环已烷热解碳。热解碳的沉积按“成核 -增长”机理有序进行 ,碳纤维、碳黑粒子都是有效籽核而促成碳的沉积。
WT5BZ]The analytical results for the pyrolytic carbons made from kerosene (Ck),gasoline(Cg),diesel oil(Cd)and cyclohexane(Cc)with XRD shown that the graphitization degree of these pyrolytic carbons was on the sequence of Ck>Cd>Cg>Cc, SEM micrographs indicated that the pyrolytic carbons was orderly aggregated on the mechanism of nucleation growth The carbon fiber and carbon black produced in pyrolyzing precursors were the crystal seeds which promoted the deposition of the pyrolytic carbons
