Low-temperature sintering process for UO2 pellets in partially-oxidative atmosphere YANG Xiao-dong(杨晓东)1, 2, GAO Jia-cheng(高家诚)1, WANG Yong(王 勇)1, CHANG Xin(畅 欣)2 1. College of Materials Science...; Abstract: Low-temperature sintering(LTS) experiments......
have thoroughly investigated the densification model of covalent ceramics with sintering additives. For example, BABINI [22] proposed a diffusion model for the oxidation of hot pressed Si3N4-Y2O3-SiO2...] calculated the apparent activation energy of hot pressed Si3N4 ceramics with Y2O3-SiO2 as sintering additive (Qd=544 kJ/mol). SANTOS et al [34] proposed the apparent activation energy of hot pressed Si3N4......
