摘要

The process of manufacturing CeO2 powders by the method of reverse deposition is investigated. The CeO2 content in the resulting products reached 99.2 wt.%. The main phase was cerium dioxide with a cubic lattice. The average particle size of the powder was about 42 μm, and the specific surface area was about 38.6 m2/g. Heating of the material from 50 to 1200°C leads to a mass loss of 18%. This mass loss is accompanied by endothermic effects with peaks on the DTA curve at temperatures of 144, 280, and 374°C. Further research directions include optimization of the properties of the obtained material, in particular its morphology, and determination of prospective application areas.
