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.
