Key Points

This study aims to determine the ionization cross-sections of specific polyatomic oxides using high-temperature mass spectrometry.
Analyzed B2O3, NaBO2, NaPO3, and KPO3 using high-temperature mass spectrometry.
Calculated ionization cross-sections using the additivity rule and correction factors.
Ionization cross-sections were determined for the tested oxides.
Use of the additivity rule led to underestimated partial pressures of molecular vapor forms.

Abstract

The ionization cross-sections of B2O3, NaBO2, NaPO3, and KPO3 were determined by high-temperature mass spectrometry. It is shown that the use of the additivity rule for calculating the ionization cross-sections leads to underestimated partial pressures of the molecular forms of vapor above the objects being studied, even when appropriate correction factors are introduced.
