| Abstract | ||
| In this research zirconium oxide samples have been prepared using microwave sintering and conventional sintering furnaces, and the effect of nano powder of zirconium oxide addition on micro-scale powder have been studied with respect to the structural and mechanical properties of the samples. The results showed that the prepared microwave samples have a fine structure with smaller grains and more uniformity, but the density of the samples are slightly higher for samples prepared in the traditional way, while the addition of the Nano-scale powder leads to obtain samples with higher density because of the low porosity. It also added the nanoparticles led to a marked improvement in the micro hardness of the samples. The results confirm that the addition of limited ratios of nanoparticles to micro-scale-powders of the same substance will lead to improvement in the microstructure and some mechanical properties that have been studied in this research. | ||
