摘　　要：综述了超细碳酸钡和碳酸锶制备方面的研究进展。详细介绍了超重力技术、固相合成技术、微乳液技术等在粒子粒度控制方面的应用和进展,同时还详细介绍了在这些方法和技术基础上通过添加各种晶形控制剂等方法对粒子形貌的控制研究近况。对目前存在的问题作了具体的讨论和分析。存在的问题是对于控制粒子形貌的机理不清楚,以及形貌和粒度不能同时得到有效控制。这些均有待于更深层的理论和实践研究。Recent research advance in preparation of ultrafine barium carbonate and strontium carbonate is summarized. The application and progress of supergravity technology, solid - state synthetic technology and microemulsion technology etc. in the terms of particle size control are both introduced detailedly. Meanwhile, on the basis of these technologies and methods, the current research situation of morphology of particles through different methods, such as adding various crystal shape control agents etc. is also minutely introduced. Furthermore, the specific discussion and analysis are made on the current existing problems. The existing problems are ： the mechanism of controlling the morphology of particles is unclear as well as the morphology and particle size can not be controlled at the same time. All of these problems are needed to be further studied theoretically and practically.
