摘要：

Potassium uptake by metallic ruthenium is enhanced and stabilized by the presence of nitrogen, accompanying a significant nitrogen uptake. The stabilized part of potassium uptake which can not be removed by evacuation at 350 °C is in a stoichiometric relation to the nitrogen uptake, suggesting that the uptake is caused by formation of a ternary compound (KN2Ru)n. Electric resistance of ruthenium film seems to be decreased slightly by formation of the ternary compound. The potassium adsorbed on this compound gives rise to an enhanced activity for the isotopic equilibration of dinitrogen. The dinitrogen nature of the ternary compound is supported by formation of hydrazine in addition to ammonia and a dinitrogen complex of ruthenium upon hydrolysis as well as ethanolysis. © 1979.
