Abstract

Good wettability between the SnO₂ and silver matrix can improve the electrical contact performance of Ag-SnO₂ materials. In this work, Ag was deposited onto the surface of Ti-doped SnO₂ particles using chemical plating to enhance the wettability. X-ray diffraction (XRD) and transmission electron microscopy (TEM) were used to characterize the Ag-coated SnO₂ particles. Scanning electron microscopy (SEM), conductivity tests, differential thermal analysis (DTA), and thermogravimetric analysis (TGA) were performed on the Ag-SnO₂ materials. Our results reveal that the chemical plating process can enhance the wettability between the Ti-doped SnO₂ particles and Ag matrix, and the Ag-coated SnO₂ particles are uniformly distributed in the Ag matrix. Both the thermal and electrical conductivity of the Ag-SnO₂ materials are significantly improved. © 2005 Elsevier B.V. All rights reserved.
