      More Details Abstract Fulltext PDF

      Al2O3:ZrO2 ceramics have been prepared from physically mixed pure oxide powders. The results indicate that careful processing of the starting powders and a two-stage sintering process can avoid expensive processing methods like hot pressing/hot isostatic pressing used for achieving high densification. The mechanical properties were measured and the resultant microstructure studied to explain the toughening behaviour of this material.

    • Microwave sintering of yttria-containing tetragonal zirconia polycrystal (Y-TZP) ceramics

      More Details Abstract Fulltext PDF

      Sintering of yttria-containing tetragonal zirconia polycrystal (Y-TZP) ceramics was performed in a single-mode cylindrical cavity applicator CMPR-250 operating at 2·45 GHz in the TM012 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 were sintered from an initial green density of 60% to final sintered density close to the theoretical density. Microwave sintering offers potential for improving microstructural properties through controlled development of uniform microstructure.
