Voltage-sensitive ceramic powder and obtained piezoresistor
The invention relates to the technical fields of ceramic dielectric materials and obtained components and parts, and specifically discloses voltage-sensitive ceramic powder and an obtained piezoresistor. The voltage-sensitive ceramic powder is obtained by doping a rare earth oxide into a ZnO-Bi2O3 voltage-sensitive ceramic system; the rare earth oxide is at least one of Y2O3, Dy2O3, Ho2O3 or La2O3; the weight of the added oxide is (1-3)% of the total weight of the ZnO-Bi2O3 voltage-sensitive ceramic system; when the voltage-sensitive ceramic powder is used for manufacturing the piezoresistor, the multi-layer-chip ceramic piezoresistor with the varistor voltage V1m that can reach 1, 000 V is realized, and the ceramic piezoresistor can replace a corresponding wafer high voltage piezoresistor; and a silver-palladium alloy electrode with a low content of palladium is used as the inner electrode, so that the low manufacturing cost of the product is realized, and the obtained piezoresistor can be widely applied to civil electronic products having requirements on low cost.
