Abstract

In one aspect, a method of producing a high purity copper-based alloy includes providing a feedstock having a composition configured to form a molten copper-based alloy having at least 50% by weight copper to a melting furnace, heating the feedstock to melt the feedstock and form the molten copper-based alloy, and bubbling an inert gas through the molten copper-based alloy with a diffusion lining formed on an interior surface of the melting furnace, the diffusion lining comprising an aluminum silicate ceramic material having a porous structure adapted to bubbling the inert gas through the molten copper-based alloy. Aspects are also directed to an apparatus for producing a high purity copper-based alloy and a method of manufacturing the apparatus.
