摘　　要：从素烧坯体吸水率、溶胶粘度、浸渍工艺三个方面对氧化铝质泡沫陶瓷的原位增韧进行了研究。研究发现:泡沫陶瓷素烧坯体的硅溶胶引入量对原位增强效果具有十分重要的影响。试验通过相关参数的调整,使硅溶胶引起的泡沫陶瓷素烧坯体的增重率由1.54%提高到2.7%时,从而将泡沫陶瓷的抗压强度则由原来的2.07 MPa增加到2.73 MPa。This paper studies the in-situ toughening of the alumina foamed ceramics from the perspectives of percentage of water absorption of biscuits, viscosity of sol and impregnation technique. The finding shows that the adoption amount of silicon sol of foamed ceramics biscuits has a significant influence over the effect of in-situ toughening. By adjusting the related parameters during the test, we manage to make the percentage of weight increase of the foamed ceramics biscuit increase from 1.54% to 2.7%, enabling the compressive strength of the foam ceramics to increase from 2.07 MPa to 2.73 MPa.
