Abstract In this research, the comparison between microwave sintering and conventional sintering on the mechanical properties and microstructural evolution of 3 mol% yttria-stabilised zirconia were studied. Green bodies were compacted and sintered at various temperatures ranging from 1200 °C to 1500 °C. The results showed that microwave assisted sintering was beneficial in enhancing the densification and mechanical properties of zirconia, particularly when sintered at 1200 °C. It was revealed that as the sintering temperature was increased to 1400 °C and beyond, the grain size and mechanical properties for both microwave- and conventional-sintered ceramics were comparable thus suggesting that the sintering temperature where densification mechanism was activated, grain size was strongly influenced by the sintering temperature and not the sintering mode.

微波与常规烧结对四方晶氧化锆性能及微观结构演变的比较

摘要 本研究比较了微波烧结与常规烧结对3 mol%氧化钇稳定氧化锆的力学性能和微观结构演变的影响。生坯在 1200°C 至 1500°C 的各种温度下压实和烧结。结果表明，微波辅助烧结有利于提高氧化锆的致密化和机械性能，特别是在 1200 °C 下烧结时。结果表明，随着烧结温度升高到 1400 °C 及以上，微波和常规烧结陶瓷的晶粒尺寸和机械性能相当，因此表明致密化机制被激活的烧结温度，
