Abstract

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.

反沉积法制备二氧化铈粉体的研究

研究了用反沉积法制备CeO2粉末的工艺。所得产物中CeO2含量达到99.2% wt.%。主要相为立方晶格的二氧化铈。粉末的平均粒径约为42 μm，比表面积约为38.6 m2/g。材料从50°C加热到1200°C会导致18%的质量损失。这种质量损失伴随着吸热效应，在144,280和374℃的DTA曲线上出现峰值。进一步的研究方向包括优化所获得的材料的性质，特别是其形态，以及确定潜在的应用领域。
