Abstract : The patent concerns the processing of barium titanate powder by confining the powder in a brass tube that has been de-aired and then inner lined with a tetrafluoroethylene coating, inserting the brass tube in a steel tube telescope fashion, swaging the steel tube down over the brass tube until a tight seal exists between the two tubes. Further swaging down the steel tube is done until the diameter of the steel tube is reduced to 0.625 inch. The barium titanate is removed from the brass tube, and hot pressed at 1900F at 10,000 pounds per square inch.
