摘要
将粒状纳米氧化锌粉体,均匀涂敷在氧化铝陶瓷基质上,低温烧结(300℃,2h)后,获得由氧化锌颗粒组成的膜层结构。SEM研究表明,膜层中的氧化锌颗粒在低温烧结时,通过物质迁移形成了烧结颈;电阻测试和分析表明:无水乙醇蒸汽浓度和温度,二者与氧化锌膜层传导电子密度之间的关系具有相似性,并进一步实现对氧化锌颗粒膜电导率的影响。
granular ZnO films, using granular ZnO nanopartieals as raw materials, was produced by low temperature sintering（300℃, 2h） on tubal fundus of Al2O3 ceramic. Mass transfer of nanopartieals and sinter neck appearing in film was attributed to low temperature sintering by SEM study. Testing and analyzing on electric resistance stated that effeetds of absolute ethanol stream on electric conductivity of granular ZnO film, as well as temperature, was earrled out by working on eonduetivlty electron density.
