Abstract

The effects of Ag content on the thermal diffusivity and conductivity of the ZrO2-Ag composites were investigated. Experimental results showed a significant increase in thermal conductivity at Ag ≥ ∼ 10 vol.%, which was primarily due to the formation of continuous Ag phase and a direct evidence was confirmed by a precipitous drop in electrical resistivity. The formation of interconnected Ag phase made the thermal conductivity of the ZrO2-Ag composites far beyond theoretical expectation.
