Microwave Sintering of Alumina Ceramics in a Single Mode Applicator,

Abstract

High purity submicron powders were sintered in a single mode cylindrical cavity applicator CMPR-250 operating at 2.45 GHz in the TMO12 mode. The alumina powders could be sintered from an initial green density of 60 % to a final density close to theoretical. Rapid heating rates at very low power level were achieved. Uniform microstructure and relatively small grain size in the microwave sintered alumina were evident. The initial results of this study demonstrate the potential applicability of a single mode applicator for sintering alumina ceramics.
