在这项研究中，微流控技术与溶胶-凝胶工艺集成在制备单分散陶瓷核燃料微球使用非活性铈作为替代钚。还提供了有关研究中使用的微流体装置和溶胶-凝胶工艺的详细信息。研究了连续相和分散相的粘度和流速对CeO 2微球粒径和粒径分布的影响。对CeO 2微球进行了X射线衍射、扫描电子显微镜、密度、粒径和粒径分布等表征。所制备的单分散粒子的粒径可精确控制在几十微米到一毫米范围内，粒径分布的变异系数小于3%。
In this study, microfluidics integrated with sol–gel processes are introduced in preparing monodisperse ceramic nuclear fuel microspheres using nonactive cerium as a surrogate for plutonium. Detailed information about microfluidic devices and sol–gel processes used in the research is also provided. The effects of the viscosity and flow rate of the continuous and dispersed phase on the size and size distribution of CeO2 microspheres were investigated. A comprehensive characterization of the CeO2 microspheres has been conducted, including the X-ray diffraction pattern, scanning electron microscopy, density, size, and size distribution. The size of prepared monodisperse particles can be controlled precisely in the range of tens of micrometers to a millimeter and the coefficient of variation of the size distribution is below 3%.
