Effect of CeO2 doping on electrical properties and microstructural of RuO2–CuO composite resistor pastes

Key Points

• Enhanced electrical properties were observed with the introduction of CeO2 doping, improving conductivity.
• Microstructural analysis indicated that CeO2 doping leads to significant changes in morphology and grain size.
• Characterization techniques used included X-ray diffraction to assess phase stability and scanning electron microscopy for microstructure.
• This work highlights the potential of CeO2 doping for optimizing composite resistors, though further application studies are warranted.
