Abstract

A method is proposed for manufacturing a pin heater that has a substantially internal insulating layer and an external conductive layer, the two layers composed of a ceramic composite structure, wherein before the pin heater is sintered, its shaping is accomplished by way of the ceramic injection molding technique or by cold combined axial/isostatic pressing.
