Abstract
In order to develop new electrical contact materials with better properties, small amounts of rare earth (RE) oxides were selected as additions into AgSnO2-based composites. The effects of different RE oxide additions with different content in the matrix on the microstructure of AgSnO2, were investigated. In general, the resulting RE oxide-doped materials are found to have better performances than their original ones. Results indicate that the newly developed AgSnO2/La2O3 materials in this paper are leading candidates for environmentally friendly electrical devices and RE oxides would play an important role in improving performance of AgSnO2.
