摘要

钍核燃料的热性能受氧化钍颗粒的形状和尺寸分布的影响。氧化钍的生产受草酸钍颗粒大小和形状的显著影响，而草酸钍颗粒通常是在沉淀过程中形成的。本研究调查了这些颗粒在微反应器系统中的合成情况。总之，研究结果表明，在草酸浓度较高的情况下，在一定程度上增加总流速会导致颗粒尺寸减小。此外，还发现提高反应温度会导致颗粒变大。

Synthesis of thorium oxalate particles in a micro-reactor: Studying the effect of temperature and reactant concentration

Thermal properties of thorium nuclear fuels are influenced by the shape and size distribution of thorium oxide particles. The production of thorium oxide is significantly influenced by the size and shape of the thorium oxalate particles which are typically formed during precipitation process. This study investigated the synthesis of these particles in a micro-reactor system. In summary, the findings showed that at high concentrations of oxalic acid, increasing the total flow rate to a certain extent leads to a decrease in the size of the particles. Also, it was found increasing the reaction temperature leads to larger particles.
