摘要：

Raman spectra of nonrandom mixtures of 18O-enriched potassium nitrate •with normal 16O-nitrate reveal that 18O, 16O interchange does not take place in the melt until the decomposition of nitrate occurs. The kinetic stability of nitrate ion with respect to oxygen exchange processes is thus established for low temperature melts. At higher temperatures sodium from the glass was detected in the potassium nitrate. Possible oxygen exchange with the glass has been inferred from the decrease in total 18O content. © 1979, The Electrochemical Society, Inc. All rights reserved.
