摘　　要：以N,N-亚甲基双丙烯酰胺为添加剂对碳酸钙晶体进行调控,用X-射线粉末衍射仪(XRD)、红外吸收光谱(FT-IR)和扫描电子显微镜(SEM)对碳酸钙晶体的晶型和形貌进行了表征。结果显示,当加入0.1gN,N-亚甲基双丙烯酰胺,并且pH值为4.0时,碳酸钙晶体的形貌呈多层球状;当加入0.005gN,N-亚甲基双丙烯酰胺,且pH值为8.0时,碳酸钙晶体的形貌出现花状,但晶体的晶型都是方解石。The N,N＇-Methylenebisacrylamide is used as additive to control the crystallization of CaCO3. The polymorph and morphology of crystals are characterized by X-ray diffraction （XRD）、fourier transform infrared spectroscopy （FT-IR） and scanning electron microscopy （SEM）. We get the following results：when the amount of 0.1g of N,N＇-Methylenebisacrylamide is added,and the pH reached 4.0,then the morphologies of crystal are multilayer pie. when the amount of 0.005g of N,N＇-Methylenebisacrylamide is added,and the pH reached 8.0,then the morphologies of crystal are flowerlike. however,only calcite crystals are formed.
