直接凝胶凝固成型SiC(M,Y)-Al_2O_3复合陶瓷材料的研究(Ⅱ)基本原理及工艺过程研究

THE RESEARCH OF PREPARING SiC(M,Y)-Al_2O_3 CERAMIC BY DIRECT GEL COAGULATION CASTING(Ⅱ)BASIC THEORY AND PROCESS

本文研究了一种新的陶瓷原位凝固成型技术 (直接凝胶凝固成型 )的基本原理和工艺过程 ,找出了影响成型工艺的基本因素 ,并且利用该成型技术制备出强度和密度较高 ,且密度均匀性好的坯体。

The thesis researched basic theory and process of a new ceramic formation method of original position congeal,which is direct gel coagulation casting(DGCC),and found basic affecting factors about the process of DGCC.Greens with high strenth,high density and very uniform were prepared by DGCC.
