Abstract

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.

在微型反应器中合成草酸钍颗粒:研究温度和反应物浓度的影响
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。

期刊介绍: Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
