采用纳米氧化铝粉体作为粘结剂,在高温高压条件下粘结球形粗颗粒,制备了透明氧化铝陶瓷。通过对500-1200 °C、5.0 GPa下制备的Al 2 O3试样的显微结构、密度和显微硬度的观察,发现添加剂纳米颗粒对样品的烧结有显着影响。高压使球形颗粒发生塑性变形,重新排列的纳米颗粒填充球形颗粒之间的空隙并相互结合,使产物致密化。添加剂颗粒还有助于晶界强化,以获得具有增强的透明度和显微硬度的样品。
Alumina nano-powder was used as the cement in bonding coarse spherical particles to fabricate transparent alumina ceramics under high pressure and modest temperature. Observations on the microstructure, density and microhardness of Al2O3specimens prepared at 500–1200 °C under 5.0 GPa provided significant effects of additive nano-particles on the sintering of samples. The high pressure initiated plastic deformation of spherical particles, rearranged nano-particles filling the clearance among spherical particles and bonding each other to densify the products. The additive particles also contribute to grain boundary strengthening to obtain samples with enhanced transparency and microhardness.
