Improved properties and reduced metal content conductive powders for high temperature sensor applications

Abstract

High temperature sensor applications have specific demands for the conductive materials used to construct devices. Traditional materials, such as platinum, palladium, and alloys impart qualities suited to their nature. However, these metals are expensive and alternative materials are generally not suited to the demands of the high temperature sensor devices. This work introduces and compares core-shell materials that impart the desirable qualities of the traditional conductive materials with improved characteristics such as thermal processability and dispersion character through engineered particulate surfaces.
