ABSTRACT:
A copper or copper alloy material having a reduced number of defects is formed by removing impurities from the material while in a molten state with a member having exposed silicon carbide particles. The member may be a bed filter formed from bed media having exposed silicon carbide particles, a porous body formed from a slurry containing silicon carbide, a porous body having at least one melt contacting surface coated with a silicon carbide material, and/or a lining having at least one melt contacting surface coated with a silicon carbide material.
