ABSTRACT:
The present invention provides a method for making an insulated electrical heating element such as for domestic appliances to heat water, etc. wherein a resistive track is embedded in a dielectric ceramic insulating material. The method includes the steps of providing a rigid base plate; printing a resistive track on one surface of a segment of flexible tape comprising fusible ceramic particles in an organic binder; adhering the other surface of the tape segment to a surface of a base plate; and placing a second segment of flexible tape of the same type on the surface with the resistive track printed thereon. Then the resulting assembly is fired to fuse the ceramic particles of the tape segments and provide a ceramic layer on the base plate with an electrical resistive track insulated therewithin.
