Abstract
This invention relates to electrically conductive ceramic materials suitable for use at high temperatures and in the presence of corrosive environments, e.g., the sodium-sulfur battery. The ceramic material comprises chromium oxide (Cr.sub.2 O.sub.3) doped with at least 0.02 mole percent lithia, wherein the chromium oxide contains less than about 0.5 mole percent of any impurity selected from the group consisting of sodium oxide and potassium oxide, based on moles of chromium oxide. The doped chromium oxide can be used as coatings on metal or metal alloy so as to form corrosion resistant current collectors which may be container/current collectors.
