    摘要: An aqueous slurry is provided for polishing or planarizing a work piece which contains a metal, the solids portion of said slurry being comprised of 1 to 50 percent by weight of submicron alpha-alumina, the remainder of the solids being of a substantially less abrasive composition chosen from the group consisting of aluminum hydroxides, gamma-alumina, delta-alumina, amorphous alumina, and amorphous silica. Also provided is a method for polishing the surface of a work piece which contains a metal wherein said aqueous slurry is used as the polishing composition during chemical-mechanical polishing.
