Original Abstract

Sintering kinetics of yttria-stabilized zirconia nanoceramics was studied by means of high-temperature dilatometry and mercury intrusion porosimetry. Green bodies were prepared by cold isostatic pressing of zirconia nanopowders with particle size 10 nm. Pressureless sintering of these bodies at 1100C resulted in the final relative density of 99% of theoretical density, and a grain size of ca. 80 nm. The influence of particle size and of pore size distribution of powder compacts on sintering behaviour was also discussed. The sintering temperature and sintering activation energy of nanoceramics was lower than that of conventional submicrometre-sized zirconia ceramics.
