圆柱形微波多模烧结腔烧结Al2O3陶瓷的性能
Microwave sintering of Al2O3 ceramic properties research in multi-mode cylindrical microwave sintering resonant cavity
摘要
Abstract
Microwave sintering is an ideal method to fabricate high property Al2O3 ceramic. In this work, a new type of multi-mode cylindrical microwave sintering resonant cavity, which can obtain higher sinter temperature in a short time and heat the whole sample, was used to sinter Al2O3 ceramic.Pure Al2O3 powder and Al2O3/MgO mixed powder were used respectively. Results showed that addition of MgO powder was benefit for the increase of relative density. While insulation the sample under 1 700 ℃ for 40 min, the relative density can achieve 97.8％ of the theory density, the Vickers hardness was 22.3 HV/GPa. It also observed that the crystal structure of microscopic particles in a large, uniform and high degree of density.关键词
