Raw materials of talc, feldsper, kaolin, alumina, silica, and zircon were used for fabrication of dense cordierite / zircon sintered body by a reaction sintering method. Density of the fabricated sintered body decreased with increasing sintering temperature ranging from 1473 to 1573K. Scanning electron microscope (SEM) and X-ray diffractometry (XRD) revealed that decreasing of the density of tpe sintered body was caused by pore formation accompanied with crystallization of cordierite. It was considered that the pore formation was due to reaction of crystalline talc with matrix phase during sintering process.textapplication/pdfdepartmental bulletin pape
