titleOfInvention | Cerium abrasives and raw materials |
abstract | The present invention is to provide a cerium-based abrasive having excellent polishing characteristics such as less occurrence of scratches and higher polishing rate. It is a cerium-based abrasive containing at least cerium oxide (CeO 2 ), lanthanum oxide (La 2 O 3 ), and neodymium oxide (Nd 2 O 3 ) as a rare earth oxide, and containing fluorine (F). While the oxide (TREO) is 90 wt% or more, the weight ratio (CeO 2 / TREO) of cerium oxide to TREO is 50 to 65 wt%, and the weight of neodymium oxide to TREO is The ratio (Nd 2 O 3 / TREO) is set to 10 wt% to 16 wt%. When such cerium-based abrasives are used, a polishing surface with little occurrence of polishing defects is obtained quickly.n n n Cerium-based abrasives, rare earth oxides, abrasive defects. |
