| Abstract: | The ZrO2-NiO material was prepared by method of chemical co-pre -ipitation. A preliminary research is made on the semiconducting and the gas-sensitive characteristics of the ceramics fived at diflerent temperatuc -es. The ceramics, which consist of ZrO2 40 mol%, when fived at 800℃ or 1200℃, is sensitive to O2. In the paper, we research the ralations between the sensitivity, the firing temperatures and the concentration of ZrO2 in the ceramics. |
