【Abstract】 When raw materials were preheated to 1 200~1 300 ℃ by electricity conventionally, microwave were inputted for 1.5~2 minutes and then Ca 4Al 6SO 16 ,Ca 3SrAl 6SO 16 ,Ca 3BaAl 6SO 16 were obtained quickly. The f CaO contents were decreased to 0. In these three minerals,Ca 4Al 6SO 16 is the easiest to obtained and Ca 3SrAl 6SO 16 is the most difficult to obtained. Fe 2O 3?Cr 2O 3?MnO 2 contributed to sulfo aluminate minerals clinkering. XRD patterns showed that the diffraction peaks of minerals are the same as that heated by conventional process.更多还原
