摘要

Heating rate plays a major role in the ceramic sintering process

especially in many new advanced sintering techniques. In this study

the effects of ultra-high heating rate up to 1200°C/s have been investigated on

various ceramic nanoparticles by

in situ

transmission electron microscopy (TEM) heating experiments to monitor the morphological changes immediately after the heating process and during the holding time. It was revealed that an ultra-high heating rate is highly effective in densifying 3 mol.% yttria-stabilized zirconia nanoparticles but was less effective for 8 mol.% yttria-stabilized zirconia or zinc oxide due to the competing diffusion mechanisms.
