Inexpensive, solderable ohmic electrodes are produced on a semiconductive ceramic body by applying to each of the opposite faces of said body a coating of a liquid composition which consists of the reaction product of fine aluminum powder and an aqueous vehicle which contains a phosphate-chromate reaction product, drying said coatings and maturing them by heating said body in air to a temperature from about 590 DEG to 950 DEG C and thereafter applying, to at least a portion of the areas coated by said matured composition, a silver electrode paste and refiring said body at a lower temperature. |
