Trans. Nonferrous Met. Soc. China 31(2021) 1818-1827 Direct carbothermic reduction of ilmenite concentrates by adding high dosage of Na2CO3 in microwave field Zhi-gang YU1,2,3, Jing-wu XIAO1,2,3, Hai... and efficient route for the utilization of ilmenite concentrates was proposed by direct carbothermic reduction in microwave field. High dosage of Na2CO3, which can be recycled, was added to accelerate......
: The synthesis mechanism of AlN by Al2O3 powders through carbothermic reduction reaction was investigated, in which the Al2O3 powders was activated by plasma assisted ball milling (PM) or by conventional ball milling (CM). The results indicate that Al2O3 powders activated by plasma assisted ball milling for 40 h can be converted to AlN totally through carbothermic reduction reaction when annealed at 1400......
