摘　　要：利用高温一维炉设备研究了悬浮态下温度对石灰石新生物相的影响。结果表明,随着悬浮态下煅烧温度的提高,石灰石煅烧后的新生物相反应活性越高,在1 100～1 200℃温度悬浮煅烧下,其新生物相活性可达到最高。1 200℃下煅烧的石灰石产物的活性约为900℃下煅烧产物活性的1.52倍;随着煅烧温度的提高,1 200℃下分解后的产物矿物结晶细小,粒度均匀,孔隙率较高,比表面积较大。Influences of different temperatures on limestone decomposition product activity under suspended state are investigated with a high temperature one-dimensional furnace.The results show that with increase of decomposition temperature,the activity of limestone decomposition product was higher under suspension state.Between 1 100 and 1 200℃,the activity of limestone decomposition product can reach the highest.The activity of limestone decomposition product under 1 200℃ was 1.52 times that of 900℃.With the increase of decomposition temperature,the decomposition product under 1 200 ℃ has smaller mineral crystallization,uniform particle size,higher porosity and greater specific surface area.
