用自蔓延高温合成技术(SHS)处理模拟含锕系元素的放射性石墨的初步研究
Preliminary Study on Treatment of Simulated Radioactive Graphite Containing Actinides by SHS Method
摘要
Abstract
Using self-propagating high-temperature synthesis technology (SHS) , the solidified body of simulated radioactive graphite containing actinides was prepared with TiO2, C, Al and CeO2 as raw material. The products were investigated by X-ray diffraction and scanning electron microscopy. The results shown that the solidification process by the SHS method maintains when ω(CeO2) ≤8% but not thorough due to the existence of TiO2 and C in the combustion products as well as some unknown diffraction peaks appeared in the XRD fingerprint; the solubility of CeO2 reached 2% ; and the morphology of the solidified body was irregular and mainly plate-like.关键词
