Date Aug. 23, 1990.Conductive ceramic materials are provided which have resistivities at room temperature of less than 10-3 OMEGA .cm. These novel materials may be made by forming a ceramic starting material comprising oxides of at least two different metals, one of which is capable of existing in a +2 oxidation state and one of which is capable of existing in a +4 oxidation state and exposing the ceramic starting material to reducing conditions. |
