Carbon impurities and properties of some palladium alloys for ceramic veneering -

Abstract

Three commercial palladium alloys (PdCuGa, PdCoGa, and PdAgSn) were melted and cast in graphite and ceramic crucibles in order to introduce small, but different levels of carbon impurities in the alloys. The solubility of carbon is known to become smaller with decreasing temperature, and in the present alloys small amounts of carbon were found to cause a substantial reduction in ductility as measured by the elongation in a tensile test.
