Tio2 Reinforced Al2o3 Composites

In this study, the effect of TiO2 addition on properties of alumina ceramics was investigated. The prepared commercial Alcoa alumina reinforced 0-15 % TiO2 were ground in ball mill for 2 h by wet milling and then powders were shaped dry pressing. After shaping operations, the samples were sintered 1500-1650 °C for 2 h. Firing shrinkage, relative density, flexural strength and hardness tests were performed and also for characterization x-ray diffraction (XRD) analysis and scanning electron microscopy (SEM) were utilized. It was seen that the TiO2 addition to alumina has effected on properties of alumina, significantly. Keywords: Alumina, TiO2, Ceramic Composites
