Overview

Experimental study demonstrates superior electrical and mechanical performance in copper slurry-based single-layer ceramic capacitors, indicating high potential for electronic applications.

Key Points

To formulate and optimize a copper-based conductive slurry on a Pb(ZrTi)O3 ceramic substrate for use in single-layer capacitors.
Formulated conductive slurries using copper powder, a SiO2-Na2O-CaO-MgO-K2O glass powder adhesive, and a terpineol vehicle.
Screen-printed the slurry onto both sides of Pb(ZrTi)O3 substrates, then degreased and sintered the samples while testing varying glass powder fractions and sintering temperatures.
Evaluated film porosity, sheet resistivity, adhesion strength, capacitance, and dielectric loss, comparing performance against two commercial single-layer capacitors.
Films prepared with 10.0 wt.% glass powder and sintered at 900 °C yielded an optimal sheet resistivity of 3.2 mΩ/sq and an adhesion strength of 12.5 MPa to the substrate.
The fabricated single-layer capacitor achieved a capacitance of 435 pF and a dielectric loss of 0.021, outperforming both evaluated commercial conductive slurries.
