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