Abstract
Applicants have discovered a new method for fine polishing surfaces of metal-soluble materials such as diamond to the submicron level. The method involves applying to the material surface a polishing medium composed of metal powder and an acidic or basic carrier. The surface is then polished by high speed rubbing to a submicron finish. Several embodiments of apparatus for performing the polishing are described.
