Abstract

This is the first paper reporting that lanthanum tungstate, earlier believed to be La(6)WO(12), is in fact La(28-x)W(4+x)O(54+delta), where tungsten dissolves in lanthanum sites to form a stable solid-state electrolyte, exhibiting proton conduction by hydration at intermediate temperatures.
