Manufacturing method of energy type ultrahigh-gradient zinc oxide piezoresistor
The invention discloses a manufacturing method of an energy type ultrahigh-gradient zinc oxide varistor. The manufacturing method comprises the following steps: preparing main additive granulation powder with uniform component distribution from main additive raw materials including Bi2O3, Co3O4, Sb2O3, MnCO3, Ni2O3, ZrO2, Y2O3, SiO2 and SnO2 by adopting a vacuum homogeneous dispersion spray granulation technology; then, subjecting the main additive granulation powder to calcining through a pre-synthesis technology so as to realize pre-synthesis; and conducting smashing and wet ball-milling toform pre-synthesized ultrafine main additive powder; subjecting the pre-synthesized ultrafine main additive powder, ZnO powder and a prepared mixed solution to vacuum homogenizing emulsification and mixing together; preparing spray granulation powder for the piezoresistor through a vacuum homogenizing dispersion spray granulation technology; and successively carrying out isostatic pressing molding, sintering, grinding, tempering, silver printing, reduction, welding and encapsulation to obtain the energy-type ultrahigh-gradient zinc oxide piezoresistor. The piezoresistor prepared by the invention is strong in energy endurance capability, high in through-current capability, good in aging performance and strong in combined wave resistance.
