Metal composite material for attachment to ceramic

摘要

A sintered solid composite material is disclosed that includes a metal and a calcium alumina compound. The metal can be a noble metal. This composite material can bond to a ceramic material, and an article is disclosed that includes a first ceramic layer bonded to a second layer of the composite material of metal and calcium alumina compound. The ceramic can be a mixed ionic and electronic conductor (MEIC), and/or have a perovskite crystal structure, and/or be a mixed oxide comprising lanthanum, strontium, cobalt, iron and oxygen. The article can be used as an electrode such as a cathode of a solid oxide fuel cell.
