                              Abrasives

                              Abrasives are materials which, by definition, enhance the surface properties of the substrate via mechanical (grinding/polishing) and/or chemical mechanisms.? PIDC material’s benefit in the mechanical mechanism include providing unique morphologies and strength for the abrasives. ?For the chemical mechanism, PIDC materials can improve the efficiency of the abrasive’s surface attack and interaction.???
