Correlation between properties of zirconia mullite and Y2O3 stabilised zirconia mullite derived by various processing techniques
Abstract Zirconia mullite (MUZ) and Y 2 O 3 -MUZ composites were synthesised by plasma melting, plasma sintering and conventional sintering techniques. Mixtures of tetragonal and cubic phases have been observed in all the processed Y 2 O 3 -MUZ composites. This observation infers that though the ava...
