Abstract
Tetragonal-tungsten-bronze-type Ba5Li2Ti2Nb8O30 ceramics have been den sified. Such materials are both ferroelectric and ionic conductor. A m aximum of epsilon'(r), appears at T-c approximate to 580K. Another sma ll peak has been found at about 305K, it probably results from a cryst allographic transition. In addition, a very strong frequency dispersio n, related to the ionic conduction, occurs at T greater than or equal to Tc.
