摘要： A coated abrasive article comprised of a backing having a layer of grains adherently bonded thereto by a binding material, wherein the layer of grains comprises abrasive grains and nonabrasive composite grains, and the nonabrasive composite grains comprise inorganic nonabrasive particles bonded together by a binder selected from the group consisting of a metal salt of fatty acid, colloidal silica, and combinations thereof. The abrasive article has an unexpected abrading efficiency, performing equal to, or superior to, a coated abrasive article containing only abrasive grains. The invention also relates to a bonded abrasive article comprising the abrasive grains and nonabrasive composite grains adhered together.

摘要： The present invention is a polishing pad for use in chemical-mechanical planarization of semiconductor wafers, and a method for making the polishing pad. The polishing pad has a body, molecular bonding links, and abrasive particles dispersed substantially uniformly throughout the body. The body is made from a polymeric matrix material and the molecular bonding links are covalently bonded to the matrix material. Substantially all of the abrasive particles are covalently bonded to at least one molecular bonding link. The molecular bonding links securely affix the abrasive particles to the matrix material to enhance the uniformity of the distribution of the abrasive particles throughout the pad and to substantially prevent the abrasive particles from breaking away from the pad.

摘要： An abrasive member comprises a substrate and an abrasive layer, which is overlaid upon the substrate and is constituted of a binder and abrasive grains dispersed therein. The abrasive grains contain aluminum oxide grains, which have the characteristics such that the sodium content, as calculated in terms of NaO, in the abrasive grains may be at most 0.1% by weight, and such that the grain diameter of .alpha.-crystal grains may be at most 5 .mu.m. The abrasive member is capable of abrading a material to be abraded such that scratches, corrosion, or the like, may not occur with the abraded material, and the abraded material having good quality may be obtained.
