Zinc oxide voltage-sensitive ceramic and preparation method thereof, as well as zinc oxide voltage-sensitive resistor and preparation method thereof
The invention provides zinc oxide voltage-sensitive ceramic and a preparation method thereof, as well as a zinc oxide voltage-sensitive resistor and a preparation method thereof. The matrix ingredients comprise zinc oxide, bismuth trioxide and cobaltic oxide. By adding cosolvents vanadic oxide and calcium fluoride, as well as a vitrification agent nitrate barium, the sintering temperature of the ceramic is reduced, the grain growth in the sintering process is effectively promoted, and the voltage-sensitive voltage threshold is reduced; by adding interface optimization agents sodium tungstate dihydrate and lithium molybdate, the grain boundary component and structure are optimized, the voltage-sensitive coefficient and performance of the material are improved, the nonlinear coefficient is improved, and the leakage current density is reduced.
