Abstract
In an aspect, a method of manufacturing a high purity copper-based alloy comprises providing in a melting furnace a feedstock and melting the feedstock. The method additionally includes bubbling an inert gas into the molten copper-based alloy to form the high purity copper-based alloy. Aspects are also directed to an apparatus and a method of fabricating an apparatus for manufacturing the high purity copper-based alloy.

A method of manufacturing an apparatus for fabricating an alloy, the method comprising:
- providing a melting furnace chamber configured to form a molten alloy;
- disposing a compacted ceramic powder layer on an inner surface of the melting furnace chamber, the compacted ceramic powder layer comprising a mixture of silica and alumina;
- and
- sintering the compacted ceramic powder layer in the melting furnace to form a diffusive lining covering substantially an entire bottom inner surface of the melting furnace chamber, the diffusive lining comprising an aluminum-silicate ceramic material having a porous structure adapted for bubbling the inert gas through the molten alloy across substantially the entire bottom inner surface of the melting furnace chamber.
A method of manufacturing an apparatus for fabricating an alloy, the method comprising:
- providing a melting furnace chamber configured to form a molten alloy;
- disposing a ceramic compacted powder layer on an inner surface of the melting furnace chamber;
- and
- selectively sintering a surface portion of the compacted ceramic powder layer, thereby forming a diffusive lining covering substantially an entire bottom inner surface of the melting furnace chamber adapted for bubbling the inert gas through the molten alloy across substantially the entire bottom inner surface of the melting furnace chamber, the diffusive lining comprising a sintered ceramic layer on an unsintered ceramic layer.
A method of manufacturing an apparatus for fabricating an alloy, the method comprising:
- providing a melting furnace chamber configured to form a molten alloy;
- disposing a compacted ceramic powder layer on an inner surface of the melting furnace chamber;
- and
- sintering the compacted ceramic powder layer using heat from a heated material disposed in the melting furnace chamber, thereby forming a diffusive lining covering substantially an entire bottom inner surface of the melting furnace chamber, the diffusive lining adapted for bubbling the inert gas through the molten alloy across substantially the entire bottom inner surface of the melting furnace chamber.
