摘要
基于氧化物陶瓷低温烧结理论,针对中低铝陶瓷(Al2O318%～75%,SiO225%～82%)采用廉价添加物配制了一种低温烧结助剂,烧结助剂包括助熔剂和活化剂两部分。此烧结助剂节能效果显著,改良产品的主要性能均达到或优于原产品。并应用XRD与SEM等研究手段,对原产品和添加烧结助剂产品的微观结构进行对比分析,发现此烧结助剂对改善产品强度,韧性,微观结构,提高化学稳定性与热稳定性均起到较好效果。
A low temperature sintering additive which comprises flux and adds all coming from cheap stuffs was developed. The objective of this study is the Mid-Low Concentration Al2O3 ceramic. The content of Al2O3 is in the range of 18% - 75%; the content of SiO2 in the range of 25 % - 82%. This additive has remarkable energy saving effect. The performances of improved products all achieve or exceed those of former products. It is indicated on the microstructure by SEM and XRD that this low temperature additive has good effects on the product strength, fallibility, improving chemical stability and thermal stability. The additive showed a prospective future for industrial popularization.
