【 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, 𝑚NiOâ€�??(1 â€�?? ð‘�?) Zr_0.9Y_0.1O_1.95 (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.
