Sentence examples for surface compound of from inspiring English sources

The results of these experiments gave rise to the idea that some kind of surface compound of the bronze type could be responsible for the increased activity which was measured with vanadia catalysts enriched with Li, Na or K. Vanadia bronzes were thus prepared as model compounds to study the interaction of vanadia with the alkali metals.
