摘　　要：采用超高温石墨化法一次性制备了品质优良的无烟煤石墨化产品,对其进行了化学成分、XRD、SEM和拉曼光谱等分析。结果表明:无烟煤超高温石墨化所得产品可以作为良好的增碳剂和还原剂;其微观结构有序性比原煤明显提高,同时石墨化程度也明显增加,但仍有少量结构缺陷。Anthracite-graphite-products with desirable quality were prepared h by ultra-high temperature graphite method, and were subsequently examined with XRD, SEM and Raman spectroscopy. The results showed that these products can be used as good carbon agent and reducing agent, microstructure ordering significantly increased when compared with the raw coal, and the graphitization degree of the products also increased significantly, while there is still a small amount of structural defects.
