%X The behaviors of mineral matters in coal at high temperature were investigated under reducing atmosphere. X-ray diffraction and SEM-EDX were employed to observe phase changes and reactions of mineral matters. It is found that the phase composition and reactions of mineral matters are basically consistent with ternary phase diagram of CaO-SiO2-Al2O3. The system of mineral matters is mainly dominated by the change of Ca-aluminosilicates. The residence time influences both the crystalline and amorphous characteristics of mineral matters. The amounts of the amorphous phase appear to be dependent on the stability of the eutectic mixture. Under reducing atmosphere, FeO-FeS system has a significant influence on the mineral behaviors and morphologies.
