摘要：

The thermoelectric properties of the composite, spherical SiO2 or Al2O3 particles dispersed in a 45Ni55Cu matrix, were measured in the temperature range from room temperature to 1073 K. The dispersed particles decrease the electrical and thermal conductivity according to an effective media theory. The Seebeck coefficient is slightly increased and differences between SiO2 and Al2O3 are not observed. The dimensionless figure of merit is nearly unchanged by the dispersion. The 20 vol.% SiO2 dispersed sample shows the highest value and reaches ZT=0.18 at 1073 K. (C) 2003 Elsevier B.V. All rights reserved.
