Absorption of Carbon Mono-Oxide by the Barium Getter Part IV. Absorption Experiments in the Temperature Range between 0°C and 250°C

Abstract

The absorption properties of the flashed barium getter beyond 0°C were studied. At low temperatures, carbon mono-oxide was apparently absorbed by the getter, while its resistance remained almost unvaried. At higher temperature than about 150°C, however, the resistance changed remarkably as the getter absorbed the gas. The ionization of the introduced gas made the absorption of the getter slightly vigorous. In the c.f. method the pressure decreased at first to a minimum value and then it began to increase, suggesting that another kind of gas was formed by the catalytic action on the getter surface. The phenomena were studied in details. The alternative introduction of carbon mono-oxide and oxygen gave a clue to the absorption state of carbon mono-oxide.
