ABSTRACT:
Boric acid, an acidifying agent, and an optional complexing agent are mixed to form an aqueous solution which is used to etch and polish metal halide. The solution is used to wet a polishing pad which is mounted on a rotating planar wheel. The metal halide is brought into contact with the pad thereby polishing the surface of the metal halide.
