ABSTRACT:
A method for removing a metallic layer from the surface of a ceramic substrate, the method including the steps of immersing the metallic coated ceramic substrate in a solution of up to 31% hydrochloric acid for a sufficient time to at least substantially dissolve or remove the metallic layer therefrom, removing the ceramic substrate from the acid solution, rinsing the ceramic substrate in a rinse solution, and annealing the ceramic substrate at a predetermined temperature for a sufficient time to at least reduce damage or defects in the surface of the ceramic substrate.
