| titleOfInvention | Preparation method of fluorinated cerium dioxide polishing powder under microwave condition |
| abstract | The invention discloses a preparation method of cerium fluoride dioxide polishing powder under microwave condition, belonging to the technical field of preparation of nano rare earth materials, and comprising the following steps: adding Ce (NO) 3 ) 3 ·6H 2 Dissolving O in deionized water, preheating by microwave, adding NH 4 F; reacting NH 4 HCO 3 Dissolved in deionized water, and preheated Ce (NO3) is added thereto 3 ·6H 2 O and NH 4 F mixed solution is subjected to constant temperature precipitation reaction under the microwave condition to generate Ce 2 (CO 3 ) 3 Precursor and continuing aging; filtering the precursor reaction solution to obtain a precipitate, drying at constant temperature, and grinding into powder; roasting the precursor powder to prepare fluorinated cerium dioxide polishing powder; the cerium dioxide powder prepared by the method has high particle crystallinity, regular shape and spherical shape, uniform particle size distribution and good dispersibility, and further improves the polishing efficiency and the polishing precision of the fluorinated cerium dioxide powder. |
