The development of different phases and microstructures of the composites were analysed to assess the relative influence of the additives on the formation of alumina-zirconia-mullite composite. Bulk density, phase combination, and microstructure of the sintered samples were examined by Archimedes method, X-ray diffraction (XRD) and scanning electron microscope (SEM), respectively. The results of the study revealed the successful formation of the alumina-mullite-zirconia composite by the reaction sintering method at temperature of 1600C. By the same token, the sample containing 6 wt.% of sintering aid shows improvement in density.}, keywords = {Alumina-Zirconia-Mullite,Composite,MgO,TiO2}, url = {https://www.acerp.ir/article_90744.html}, eprint = {https://www.acerp.ir/article_90744_2541dfe857d38e3e7c3b98948a7e6481.pdf} }
