| titleOfInvention | Cerium oxide polishing powder and preparation method thereof |
| abstract | The invention discloses cerium oxide polishing powder. The purity TREO of cerium oxide CeO2 is more than or equal to 99.95%; cerium oxide is CeO2 powder with crystal form being a uniphase cubic crystal system; cerium oxide is shaped like a round cake with the average particle size of 1mum. The invention further discloses a preparation method for the cerium oxide polishing powder. The preparation method comprises the steps of preparation of cerium chloride, precipitation, dehydration, roasting, smashing and the like. Compared with the existing preparation method, the polishing powder prepared by adopting the method is cerium oxide powder, F is not required for introduction in the preparation process, and the preparation method has the advantages of being simple in process, low in cost, and free from waste water; the cerium oxide polishing powder has the advantages of having no scratch in the polishing process of products, being high in polishing precision and the like. |
