琼脂含量对Li2TiO3陶瓷微球制备工艺的影响
Effects of agar on the fabrication of Li_2TiO_3 solid tritium breeding ceramic pebbles
摘要
Abstract
Li2TiO3 ceramics stands out as one of candidates for tritium breeding materials in ITER test blanket module（TBM）,thanks to the excellent properties,such as a greater lithium atom density,better chemical stability,lower tritium retention,better compatibility with structural materials,and excellent tritium release performance at a lower temperature.This paper introduces the fabrication of Li2TiO3 ceramic pebbles using Li2CO3 and TiO2 as raw materials,and agar as adhesive by direct wet method and the investigation into the molding process of the pebbles and the effects of agar and water amount on the sphericity and microstructure of Li2TiO3 ceramic pebbles.The results show that,when fabricated with the presence of the amount of agar of 3wt% and at the temperature of water bath of 85 ℃,the Li2TiO3 ceramic pebbles exhibit a higher sphericity.Li2TiO3 ceramic pebbles sintered at 1 300 ℃ show a higher density,up to 84.9% of theoretical density,and the pebbles boast rich micropore structure with the pore size varying from 0.03μm to 0.20 μm.关键词
