以具有不同晶形结构的两种石灰石原矿为研究对象，通过改变煅烧温度和保温时间获得不同活度的煅烧产物，借助X射线衍射分析煅烧产物的物相组成，依靠扫描电子显微镜观测其微观形貌，以酸碱滴定法测量其活度，考察原矿中石灰石结晶形貌对石灰石分解的影响。结果表明：层状结构的石灰石比颗粒状结构的石灰石具有更高的热分解温度，且分解速率较慢；在相同的煅烧条件下，前者的煅烧产物较后者具备更高的活性。在相同的煅烧温度下保温60 min时，CaO晶体具有疏松的多孔结构并且存在大量的缺陷，此时的活度最高，活度值达到328.6 mL。

Based on two limestone of different crystalline structure as the research object,by changing the cal-cining temperature and holding time for different activity of calcined product,with the X-ray diffraction analy-sis characterize the phase composition of the calcined product,rely on the scanning electron microscope obser-vation its microstructure,with acid-base titration measurement activity,studying the effect limestone crystal morphology on limestone decomposition.The results showed that:Layers structure of limestone than granular structure of limestone has higher thermal decomposition temperature,and the decomposition rate is slow. Un-der the condition of the same calcination,The calcined product of the former have a higher activity than the latter. In this experiment,at the same calcination temperature insulate 60 min,CaO crystal has a loose and po-rous structure,there are a large number of defects,at this time,the activity is highest,up to 328.6 ml.
