Method for removal of carbonaceous residues from ceramic structures having internal metallurgy

摘要

A process for removing organic materials from an article formed from a slurry of glass and/or ceramic particles, resin binder, and a solvent for the resin binder, the process involving including in the slurry a particulate catalyst selected from the group consisting of Cu, Cu2O, CuO, Cu2SO4, CuCl2, Cu organometallic compounds, and mixtures thereof, the catalyst promoting a rapid and complete removal from the shaped article when heated of the organic materials of the slurry.
