| Abstract: | ZnO semiconductive ceramics has been used variously as multifunctional materials. ZnO conductive ceramics with additives MgO and Al2O3 were produced. The effects of additive contents, sintering temperature and cooling rate on resistive characteristics in ZnO ceramics were studied. It was shown that Al2O3 content and sintering temperature were the main cause to affect the resistivity. And MgO content and cooing rate could affect the property ofresistivity with temperature. It was analyzed according to defect aqation. |
