摘　　要：以不同纯度的自制氢氧化锶为原料与盐酸充分反应,经提纯、结晶,制备六水氯化锶(SrCl2·6H2O)。通过X射线衍射(XRD)和场发射扫描电子显微镜(FESEM)对SrCl2·6H2O的结构、形貌进行表征,通过能谱仪(EDS)和差热-热重分析仪(TG)对SrCl2·6H2O进行元素含量和热失重分析,并将制备的样品与中华人民共和国化工行业牙膏用氯化锶标准进行对比。结果表明,高纯氢氧化锶与分析纯盐酸制备的SrCl2·6H2O达到牙膏用标准。Strontium chloride hexahydrate(SrCl2·6 H2O) of the toothpaste grade was prepared with the sufficient reaction of self-purified strontium hydroxide and hydrochloric acid after purification and crystallization.The structure and morphology of SrCl2·6 H2O were characterized by X-ray diffraction(XRD),scanning electron microscope(SEM).The elemental analysis and thermogravimetic analysis of SrCl2·6 H2O were measured by X-ray energy dispersive spectroscopy(EDS)and thermal gravimetric analyzer(TG)respectively.The results indicated that the SrCl2·6 H2O prepared by high-purified strontium hydroxide and analytical pure hydrochloric acid can reach the toothpaste grade compared with the standard of strontium chloride of chemical industry of the People’s Republic of China.
