Proton Conductivity of Ceramic Tungstoantimonic Acid

Article Preview

Abstract:

Ceramic samples of tungstoantimonic acid (TAA) were obtained by ion exchange of sintered potassium tungstoantimonate, KWSbO6, in acid solution. The ac conductivity of these samples is by 2 orders of magnitude higher than the conductivity of pressed powder of tungstoantimonic acid. The conduction mechanism in this material seems similar to the one in polyantimonic acid (PAA), though the conductivity of TAA is by 1.5 orders of magnitude lower than that of PAA. Based on these results and literature data on the conductivity of PAA and its derivatives, the directions for the search for materials with improved proton-conducting properties in this family of compounds are discussed.
