V 86 Volkov, V. L. The ion emission properties of MxV205 (M = Li, Na, K, Cs) bronzes were studied at temperatures in Sodium Aluminum Vanadium beta-Bronzes / V. L. Volkov, O. I.

The AG (AI), AH (AI), and AY; (AI) of the bronzes were found to vary in a complex manner with AI content, passing through extrema near y = 1 as a result of the structural ordering of A13+ ions. The temperature dependences of A G (AI) show changes in slope between 303 and 318 K, attributable to redistribution of the AI 3+ ions over the possible crystallographic sites in the beta-bronze structure Полный текст |
