High temperature electrically conducting ceramic heating element and control system
Author(s): Halbach, C. R.; Page, R. J.
Abstract: Improvements were made in both electrode technology and ceramic conductor quality to increase significantly the lifetime and thermal cycling capability of electrically conducting ceramic heater elements. These elements were ...
