Originální abstrakt

Ceria powder was dry-milled to sub-micrometric particle sizes and used in the preparation of ceramic mixture for injection moulding. Specimen bodies were injection moulded in the shape of rectangular bars. The sintering kinetics of these bodies was studied in a dilatometer under various sintering conditions and also by the rate-controlled sintering method. Sintering the injection moulded CeO2 to a density of 7.08 g.cm-3 (99.3% TD) was possible already at a temperature of 1400C, and the highest density value (99.8% TD) was obtained at a heating rate of 2C.min-1 and a holding time of 1 hour at 1500C. Using heating rates of over 5C.min-1 had an adverse effect on the density obtained. Applying the rate-controlled sintering (RCS) method did not lead to any decrease in the grain size if compared with temperature-controlled sintering (TCS).
