摘要	Carbothermic reduction of celestite is the first procedure of universal process for preparing SrCO3. However, only one species as SrS without SrO can be found in reduction product of SrSO4 by solid carbon at the reduction temperature below 1273 K, and less effect of factors such as C/O ratio and reaction temperature on the reduction of SrSO4 is found. An investigation on reduction of SrSO4 is carried out. The experiment result reveals that the reduction of SrSO4 is a reduction-decomposition process: SrSO4 is first reduced to SrSO3, and then, the SrSO3 was decomposed into SrSO4 and SrS below 1273 K or SrO and SO2 above 1273 K. Kinetic analysis of the reduction of SrSO4 reveals that the reduction of SrSO4 is controlled by step of interface reaction, and its activation energy is 105.4 kJ/mol.
