| Abstract: | Using MgO-TiO2-La2O3 sintering additives,95 alumina ceramics are prepared by the low-temperature sintering technology.We investigate that temperature and additive content have an important effect on the mechanical properties of alumina ceramic sintering and carry on phase analysis.The results showed that when MgO content is 1.5wt%,TiO2 for 1.0wt% and La2O3 for2.5wt% for alumina ceramic at 1500℃ for 2h,flexural strength and hardness are 348.94 MPa and 79.6HRA. |
