摘　　要：对石煤提钒焙烧过程相变机理的研究是在石煤提钒工业生产中的主要研究课题之一。借助X衍射分析手段 ,详细研究了方山口石煤无添加剂焙烧和加添加剂氯化钠焙烧过程中 ,矿样中主要物相随温度升高的变化。By means of X ray diffraction analysis, the change of transformation of phase with the temperature increasing, during the roasting of Fanshankou bone coal was researched,both with and without NaCl as additive. The major reaction about phase transformation during the bone coal roasting added NaCl was obtained.
