摘　　要：在NaF和BaSO_4存在时,用DTA-TG研究了CaCO_3分解温度和过程的变化,用IR和XRD等研究了C_2S的形成。实验表明,NaF降低了CaCO_3的分解温度和C_2S的形成温度,而BaSO_4的矿化作用较差。The author researches the temperature of CaC0_3 calcining and its process changing with DTA-TG method, and C,S forming by IR and XRD method and its like,when NaF and BaS0_4exist in raw mix. The experiment demonstrates the temperature of GaC0_3 calcining and of C_2S forming are lowered due to NaF existing and a worse mineralizing effect of BaS0_4 is shown.
