摘要

该研究致力于在 2130 至 2650 K 的温度范围内，从不同材料（钼、钽和钨）制成的耐火坩埚中强化 CeO2 蒸发。通过四极质谱法和能量色散 X 射线光谱法获得了蒸发产物收集器上沉积的蒸气和薄膜的成分数据。测量了 2150 至 2220 K 范围内 CeO2 蒸汽与温度关系的近似系数之一。这项研究对利用高生产率耐火氧化物蒸发的各种技术（包括等离子体质量分离方法）具有重要意义。

Enhanced CeO2 evaporation from refractory crucibles (Mo, Ta, W)

The study is devoted to enhanced CeO₂ evaporation in the temperature range between 2130 and 2650 K from refractory crucibles made of different materials: molybdenum, tantalum, and tungsten. The composition datum of vapor and films deposited on collectors receiving evaporation products were obtained by quadrupole mass spectroscopy and by energy-dispersive X-ray spectroscopy. One of approximation coefficients of the temperature dependence of CeO₂ vapor in the range between 2150 and 2220 K was measured. The study is of interest for a variety of technologies utilizing refractory oxide evaporation with high productivity, including the plasma mass separation methods.

期刊介绍： This journal serves the circulation of new developments in the field of basic research of heat and mass transfer phenomena, as well as related material properties and their measurements. Thereby applications to engineering problems are promoted. The journal is the traditional "Wärme- und Stoffübertragung" which was changed to "Heat and Mass Transfer" back in 1995.
