| Abstract: | Al2O3 ceramics are fabricated using high-purity Al2O3 powder,Mg(NO3)2 · 6H2O, and Y(NO3)3 ·6H2O as the raw material,sintered at 1500℃, 1600℃, 1700℃ without pressure. Effects of sintering temperatures and additives on the final density,hardness and microstructure are studied. The results show that the effects of sintering additives are influenced by sintering temperatures,then hardness is effected. |
