Zinc oxide piezoresistor dielectric material and preparation method thereof
The invention provides a zinc oxide piezoresistor dielectric material. The zinc oxide piezoresistor dielectric material is prepared from, by mole, a main component including 100 parts of ZnO and additive components including 0.05-1.3 parts of Sb2O3, 0.05-1.3 parts of Co2O3, 0.05-1.3 parts of Bi2O3, 0.05-1.3 parts of MnO2, 0.05-1.3 parts of Cr2O3, 0.05-1.3 parts of SnO2, 0.05-1.3 parts of SiO2, 0.05-1.3 parts of Ni2O3, 0.05-0.6 part of boric acid, 0.05-0.6 part of AgNO3 and 0.05-0.6 part of Sm2O3. The invention further provides a preparation method of the zinc oxide piezoresistor dielectric material. The zinc oxide piezoresistor dielectric material is high in pulse impact resistance, and is expected to be applied to anti-thunder overvoltage protection of a power lightning arrester or other power electronic circuits. The zinc oxide piezoresistor dielectric material can be sintered at medium-and-low temperature, the manufacturing process is simple, the cost of the zinc oxide piezoresistor material is greatly reduced, and the requirements of energy saving and environment friendliness are met.
