ABSTRACT:
A heat generating element particularly well suited for use in an electrical space heater and method of making same include an electrically nonconductive substrate on which is coated a layer of an electrically nonconductive ceramic material having finely divided, micron size metallic particles dispersed therein. A path of electrical conductivity is established in the otherwise nonconductive ceramic material by burnishing the surface of the ceramic material between two separated points. Thus, as electrical current flows along the burnished path, heat will be generated due to the electrical resistance thereof.
