摘 要：<正>The effect of LiF on the densification and mechanical properties of hot-pressed Dy-a-sialon ceramics was studied. Comparatively, without LiF as sintering additive, the pure Dy-a-sialon ceramic should be sintered at 1750℃. When LiF is used, the sintering temperature of the Dy-a-sialon is greatly lowered to 1500 1650℃. Obviously, the addition of LiF has a strong effect on the improvement in densification. Meanwhile, the resultant Dy-a-sialon has no significant changes in the mechanical properties.
