Title: | Bi, Pr and V-free Novel ZnO Voltage-sensitive Ceramic Material and Preparation Method Thereof |
Description: | The invention relates to a Bi, Pr and V-free novel ZnO voltage-sensitive ceramic material and a preparation method thereof. The ZnO voltage- sensitive ceramic material is composed of zinc oxide and a modified additive, wherein the content of zinc oxide is 86.5-99.7mol%, and the content of the modified additive is 0.3-13.5mol%; the modified additive comprises 0.1-10mol% of CaCO3, 0.1-1.5mol% of Co2O3, 0.1-1mol% of Cr2O3 and 0-1mol% of La2O3. The voltage-sensitive voltage of the novel ZnO voltage-sensitive ceramic material is 360-700V/mm, the nonlinear coefficient (I-V nonlinear coefficient) alpha is greater than or equal to 18, the leak current IL is less than or equal to 1mA, and the comprehensive property is excellent. The material is equivalent to that of existing Bi-containing zinc oxide voltage-sensitive ceramic industrially produced in property. |
