【Abstract】 This paper studied the influence of different oxides on the stability of CaSO 4 at high temperature.The result shows that under 1 050 ℃,CaSO 4 almost does not decompose.But most of it decomposes above 1 250 ℃.It also shows that alkaline earth metals oxides additive can delay the decomposition of CaSO 4 ,and Si Al complex oxides additive can increase the stability of CaSO 4.The Si Fe Ca complex additive has the marked action on the restrain of the decomposition of CaSO 4 at high temperature.更多还原
