Dm. Liu et Wh. Tuan, MICROSTRUCTURE AND ITS INFLUENCE ON THERMAL AND ELECTRICAL-CONDUCTIVITY OF ZRO2-AG COMPOSITES, Materials chemistry and physics, 48(3), 1997, pp. 258-262
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.
