摘要:
Disclosed is a metal coating film formed by applying a metal particle dispersion containing meal fine particles, water and a dispersing agent having a molecular weight of 2,000-30,000 to the surface of a base and firing it. This metal coating film is composed of an alloy containing (1) Ag and (2) at least one metal selected from the group consisting of Au, Pt, Pd, Ru, Ir, Sn, Cu, Ni, Fe, Co, Ti and In, in which alloy the Ag content is 80-99.9 at% relative to the total alloy and the average crystal grain size is 0.2-5 μm. By having such a constitution, the metal coating film has low surface roughness, excellent smoothness and excellent denseness, while exhibiting excellent adhesion to the base and excellent etching properties. Also disclosed are a method for forming such a metal coating film, and a metal wiring obtained by patterning such a metal coating film. The coating film is fired at a temperature not more than 700˚C.

摘要:
A process for producing a dispersed-oxide-containing alloy in which oxide particles of one or more additive metals are dispersed in a matrix metal. The process, which is for producing a dispersed-oxide-containing alloy, comprises (a) a step in which a powder or wire of an alloy comprising a matrix metal and one or more additive metals is produced, (b) a step in which the alloy powder or wire is introduced into a high-energy ball mill together with water and the contents are agitated to thereby oxidize the additive metals contained in the alloy powder with water and form dispersed particles, and (c) a step in which the alloy powder or wire after the oxidization is shaped and solidified. It is useful especially for the production of a dispersed-oxide-containing alloy in which the free energy of oxide formation of the matrix metal is higher than the standard free energy of formation of water and the free energy of oxide formation of the additive metals is lower than the standard free energy of formation of water.
