Constitution and properties of ceramized fireclay refractories: I. Constitution

  • S P Chaudhuri

A poor-grade fireclay was mixed with three nucleating agents, namely Cr2O3, V2O5 and TiO2. The fireclay and oxide mixed fireclay were fired at 1300°C for 1 h, cooled down to room temperature and then heat-treated at 1150°C for 15h. These were also heat-treated at 1150°C for 15 h after cooling down to 1150°C from the peak temperature. The heat-treatment caused ceramization of the glassy phase in the fireclay samples, and the samples, mineralogical composition and microstructure were investigated. Ceramization brought about significant changes in the microstructure only.
