Abstract
In order to improve the dispersion of SnO2 in Ag matrix, Ag/SnO2 contact materials wasprepared by optimized chemical deposition process. The micro-morphology and phase of theAg/SnO2 contact materials were tested by metallographic microscope and XRD. The results showedthat the combination of mechanical stirring and ultrasonic stirring can effectively improve thedispersion of SnO2 in Ag matrix, the Vickers hardness, conductivity and density of the Ag/SnO2contact materials with 88% Ag content are 114.4HV, 77.4% IACS and 9.75g/cm3 respectively. Theseprovide data reference for preparation of Ag/SnO2 contact materials with uniform SnO2 distributionin Ag matrix.
