The solubility of Aluminum (Al)-doped ZnO ceramic was determined to be 0.9 atomic ratio percent (at.%), and the ZnAl2O4 was formed once the Al content achieved 1.0 at.% or above. The resistivity decreased at an Al content of 00.8 at.% to a minimum of 1.45 x 10-3 O, while increased at a range of 1.06.0 at.%. The resistivity increased and decreased with temperature when the Al content was below and above 2.0 at.%, respectively. The activation energy increased from -489.5 to -65.0 eV and from 66.0 to 293.8 eV when the Al doping content was below and above 2.0 at.%.
