摘要：
SiO2-Si3N4 ceramic composites with high flexural strength and low porosity were fabricated using gelcasting, a near-net shape fabrication technique, by varying solid loading, Si3N4 content, monomer content and ratio of monomers. Mathematical models were developed using response surface methodology to determine the effect of the process parameters. The influence of solid loading, Si3N4 content, monomer content and monomer ratio were studied with the help of RSM using a central composite face centered design with 6 centre points on SiO2-Si3N4 ceramic composites. The optimal values for maximum flexural strength and porosity were 94.62 MPa and 41.52% respectively. (C) 2017 Elsevier Ltd. All rights reserved.
