Abstract

Nanostructural ZnO ceramics was prepared using Al doped ZnO nano-powders by low- Temperature HPing at 950°C for 3h. Al-doped ZnO nano-powders was obtained by chemical processing of both co-precipitation and spry drying at 120°C. Power factor of the prepared ZnO ceramics is 5.0x10-4Wm-1K-2, , which increased ca. 20% by HP sintering at 950°C. The prepared nanostructural ZnO ceramics showed lower thermal conductivity than that of normal sintered ceramics at the lower temperature range.
