Original Abstract

The kinetics of sintering of ceramic materials based on alumina, zirconia, ZTA and ATZ was studied at a constant rate of heating and by means of the rate controlled sintering method. Ceramic samples were prepared by cold isostatic pressing and powder injection moulding. The sintering was performed in air atmosphere either in a high-temperature dilatometer or in a high-temperature superkanthal furnace. It was found that the alumina-based ceramics sintered at a higher temperature than those based on zirconia. The resultant relative densities were higher for the ceramics prepared by cold isostatic pressing then for those prepared by injection moulding. Slow rates of heating (2°C/min) were more convenient for reaching higher relative densities in the case of injection moulded ceramics. The maximum relative densities and flexural strength of ceramics were obtained at one hour’s delay at a temperature of 1500°C.
