摘要

摘要采用高温差分质谱法研究了存在碳的 Y2O3 的蒸发过程。在 1950-2200 K 的温度范围内，Y2O3-C 体系上方的蒸气中含有 YO 和原子钇。温度升高时，Y2O3-C 体系上 YO 蒸汽的分压与单个 Y2O3 上 YO 蒸汽的分压相比会降低，从而导致该体系中氧化钇的活性降低。

Mass Spectrometric Study of the Interaction of Y2O3 with Carbon at High Temperatures

Abstract

The evaporation of Y₂O₃ in the presence of carbon was studied by high-temperature differential mass spectrometry. In the temperature range 1950–2200 K, the vapor above the Y₂O₃–C system contains YO and atomic yttrium. At elevated temperatures, the partial pressure of YO vapor over the Y₂O₃–C system decreases compared to the partial pressure of YO vapor over individual Y₂O₃, leading to a decrease in the activity of yttrium oxide in the system.
