【 摘 要 】
In the present study, microwave energy (2.45 GHz) has been used to prepare nickel oxideâ€�?�yttria stabilized zirconia (NiOâ€�?�YSZ) composites of composition, ð‘šNiOâ€�??(1 â€�?? ð‘�?) Zr0.9Y0.1O1.95 (ð‘�? = 0.2, 0.3, 0.4, 0.5 and 0.6), from a precursor obtained by mixing NiO, Y2O3 and monoclinic ZrO2 in their stoichiometric ratio. The composites have been prepared by conventional processing also to compare the products with those of microwave processed products. During comparison, it was observed that NiOâ€�?�YSZ composites of each composition obtained by microwave processing had cubic phase of YSZ while in the conventionally prepared composites of compositions, ð‘�? = 0.2 and 0.3, monoclinic, tetragonal and cubic phases of zirconia existed instead of its pure cubic phase. The composites were reduced to yield Niâ€�?�YSZ.
