The Comparison of MgO and TiO2 Additives Role on Sintering Behavior and Microstructures of Reaction-Sintered Alumina-Zirconia-Mullite Composite %K Alumina-Zirconia-Mullite %K Composite %K MgO %K TiO2 %R 10.30501/acp.2015.90744 %X Alumina-Mullite-Zirconia ceramic composites were prepared by reaction sintering of alumina, zircon mixture and the sintering aids of magnesia and titania at temperatures of 1400 and 1600 C for 2 hours. 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. %U https://www.acerp.ir/article_90744_2541dfe857d38e3e7c3b98948a7e6481.pdf
