摘要
利用不同O2浓度的模拟富氧气氛烧成陶瓷试样,采用TG/DSC、XRD、SEM、三点弯曲及阿基米德原理进行了烧成气氛中O2浓度及组分-SiO2/Al2O3变化对陶瓷试样的结构及机械强度影响研究。结果表明:富氧气氛中O2浓度的增加及组分中SiO2/Al2O3的增加对于陶瓷试样的结构改善、机械强度提高均具有促进作用。与普通空气烧成相比,富氧技术的应用能适当的缩短烧成周期,给陶瓷工业带来一定能源节约。
Different simulated oxygen-enriched atmosphere with varying O2 concentration was employed to prepare ceramics. The effects of O2 concentration in the oxygen-enriched atmosphere and SiO2/ Al2O3 on the structure and mechanical properties of ceramic specimens were investigated with TG / DSC,XRD,SEM,3-point technique and Archimedes method. The results showed that the simulated oxygen-enriched atmosphere with increased O2 concentration and increasing SiO2/ Al2O3 in the ceramic blank were beneficial to the structure development and mechanical properties enhancement of the samples. In comparison with conventional air- sintering,the utilization of oxygen-enriched technique could shorten the sintering cycle properly,subsequently bringing about substantial energy conservations.
