Zusammenfassung:A chemical coprecipitation process for preparing compound powder of pressure-sensitive ZnO resistor includes such steps as dissolving the sulfates of all components in water, then adding powdered ZnO, uniformly dispersing, adding precipitant, coprecipitation at pH=8-9; after separating, washing, drying and thermolysis, obtaining the compound powder. It can be used to make pressure-sensitive ZnO resistor by electric ceramic technology.
