| Abstract: | In this paper,MnO2-TiO2-CaO-La2O3 composite additives were used as a sintering agent of alumina ceramics.The effects of the amount of MnO2 on the properties of 95 alumina ceramics were studied.The results show that alumina ceramics sintered in air at 1550℃ shows the best combination properties when the amount of MnO2 is 3.0%.The bulk density of alumina ceramics reaches 3.76g·cm-3.The bending strength and Rockwell hardness(HRA) of the samples reach 355.22MPa and 84.3 respectively. |
