| Abstract: | At the atmosphere pressure,SrCO 3 is decomposed into SrO and CO 2 when heated. Based on thermodynamics analysis,thermal decomposition of SrCO 3 was studied on different conditions. The results show that decomposition temperature of SrCO 3 decreases when Al 2O 3 or C are added respectively, or partial pressure of the system is lowered. The effect of adding Al 2O 3 on the temperature is the greatest among the tested factors. When carbon is added to SrCO 3, not only the decomposition temperature of SrCO 3 can be lowered but also CO produced can be reused as a by-product. |
