Improved Cu/Glass Ceramic Mixtures

      A process has been developed to improve the wetting between
glass ceramic particles and Cu particles during sintering of
structures containing both constituents.

      The process involves dissolving Cu oxide into a glass, mixing
the glass with Cu powder, and firing through a sintering cycle such
that the atmosphere is reducing to Cu.  This process will cause well
bonded Cu particles to precipitate out on the surface of the glass
particles [1,2].  This structure, comprised of Cu particles uniformly
distributed on the glass surface will enhance sintering of the
Cu/glass ceramic composite material and also increase the interfacial
adhesion.
