“…Allen et al (1993) developed a TIC with an ultra-small spacing, having rather high electric output at the electrode temperature of 1400-1600 K. In the initial state the TIC electrodes are completely closed, and the ultra-small spacing was automatically produced on heating the electrodes up to operating temperatures due to the difference in coefficients of thermal expansion (CTE) of the electrode materials.…”

The paper presents peculiarities of the technology for creating a small interelectrode spacing in thermionic converters (TIC) using two-phase graphite-cesium and graphite-cesium-barium systems.Optimum conditions are discussed for cesium and barium intercalation into oriented graphite (load-bearing member) placed inside the converter interelectrode gap to obtain a stable ultra-small spacing.Principle design diagrams of a close-spaced TIC are presented, and their basic technical characteristics are assessed.The analytical relationship between the members of the load-bearing unit based on the graphite-cesium system and the TIC interelectrode spacing being formed is established from calculations and experiments.
