Abstract

Thermionic emission of oxygen negative ions, O^-, from a bare surface of yttria-stabilized zirconia (YSZ) was studied with a quadrupole mass spectrometer equipped with an energy filter, which is capable of detecting negative ions. Emission characteristics of O^- ions were investigated at temperatures ranging from 725 to 925°C under pressures of 1.4 × 10^-4 to 3.2 × 10^-4 Pa. Mass spectra of emitted negatively charged particles showed that O^- ions are emitted into a vacuum from the bare YSZ surface at elevated temperatures. By examining the energy distributions of O^- ions, the number of emitted O^- ions was found to increase with the temperature of YSZ.
