Abstract

789,336. Making ceramic piezo-electric elements. ERIE RESISTOR CORPORATION. Nov. 18, 1955 [Dec. 27, 1954], No. 33035/55. Class 40 (8). Thin electroded ceramic (e.g. barium titanate) elements 1 are made by casting a number of ceramic bars 4 in a matrix 7 of settable plastic (e.g. an epoxy resin) and cutting wafers 8 off the matrix in the direction shown. Both sides of the wafer are coated with a metallic ceramic paint. When the paint is fired the plastic disintegrates, leaving the ceramic elements coated on both faces, but not on the edges. If other metal coating processes which do not involve firing are used, the elements may easily be broken away from the plastic. Two of the elements 1 may be cemented face-to-face to form a bending element.
