Originální abstrakt

The paper is dealing with fast sintering of advanced ceramic materials, namely tetragonal zirconia (particle size 80 and 140 nm) and α-alumina (particle size 150 and 270 nm), in conventional resistance furnace. This approach is made possible by special superkanthal furnace, which is capable of reaching a heating rate of 200 °C/min. Samples obtained through cold isostatic pressing (CIP) and fast sintering reached relative density up to 97.8 % t.d. for zirconia and 99.9 % t.d. for alumina, without forming any cracks in samples. Surprisingly, final relative density in the case of tetragonal zirconia with 80 nm particle size was higher for samples with larger pores in the green body (CIP at 25 MPa) than for samples with smaller ones (CIP at 300 MPa). This behaviour is different from conventional sintering and leads to considerations of heat transfer mainly by radiation.
