Abstract
MgxZn1-xO:Al ceramics with high density and low resistivity were prepared by solid-state sintering process. The influence of Mg content on structure and properties of MgxZn1-xO:Al ceramics were studied. The Mg content influence mainly the phase structure and grain growth, as a result influence the relative density and resistivity of MgxZn1-xO:Al ceramics. The MgxZn1-xO:Al ceramics with high density and homogeneous structure can be made when the Mg content is over 0.3. Mg content effect obviously the condctivities of MgxZn1-xO:Al ceramics due to the variation of the carrier concentration and the mobility deriving from the change of micro structure and Al-doping efficiency when the Mg content is under 0.2.
