Abstract
Abstract In this paper, MnO2 is used as the sintering aid for alumina (Al2O3) ceramics, and 3D printing and atmospheric sintering are used to study the sintering performance of alumina ceramics at 1300 °C, 1350 °C and 1400 °C by the content of different manganese oxide. Impact. Through experimental analysis, it is concluded that when the content of MnO2 sintering aid is 0-2.4 percent, it can promote the sintering performance of alumina ceramics; and when the sintering temperature is 1350 °C, alumina ceramics has better performance under SEM electron microscope morphology.
