Abstract
The effects of Ag content on the thermal diffusivity and conductivity of the ZrO2-Ag composites were investigated. Experimental results show ed a significant increase in thermal conductivity at Ag greater than o r equal to similar to 10 vol.%, which was primarily due to the formati on of continuous Ag phase and a direct evidence was confirmed by a pre cipitous drop in electrical resistivity. The formation of interconnect ed Ag phase made the thermal conductivity of the ZrO2-Ag composites fa r beyond theoretical expectation.
