Abstract

Experimental sintering studies on Al2O3 powder (200 nm and 600 nm) were done at a heating rate of 1600 °C/min. The microstructural changes of specimens were examined and corresponding detailed data on the densification and grain size as a function of sintering time were presented. The grain-growth transition behavior during sintering was discussed. The results showed that the neck growth caused principally by surface diffusion could be negligible within 2 min. With subsequent increases of sintering time, grain growth promoted by grain boundary and lattice diffusion occurred.
