Abstract
Sintering of yttria-containing tetragonal zirconia polycrystal (Y-TZP) ceramics was performed in a single-mode cylindrical cavity applicator CMPR-250 operating at 245 GHz in the TM(012) mode. High heating rates at low power levels were achieved. Rapid heating and cooling resulted in a fine-grain microstructure.High-purity submicron Y-TZP powders we re sintered from an initial green density of 60% to final sintered den sity close to the theoretical density. Microwave sintering offers pote ntial for improving microstructural properties through controlled deve lopment of uniform microstructure.
