In this study, to increase the strength and enhance the sintering property of Al2O3, Y2O3 and La2O3 were added; the effects of these additions on the sintering characteristics of Al2O3 were observed. Adding 1 % of Y2O3 to Al2O3 repressed the development of abnormal particles and reduced the grain boundary migration of Al2O3, curbing pores to capture particles; as such, the material showed a fine microstructure. But, when over 2% of Y2O3 was added, the sintering property was reduced because of abnormal particle grain growth and pore formation in particles. Adding 1 % of Y2O3 and La2O3 to Al2O3 led to the development of abnormal particles and formed pores in the particles; when over 3% of La2O3 was added, the sintering property was reduced because the shape of the Al2O3 particles changed to angled plates.
