Process for producing a zirconia refractory heating element

摘要

A process for producing a laminate-shaped zirconia refractory heating element which generates heat by passing a current therethrough or by induction heating including the steps of incorporating a flexible binder in a filler composed of zirconia fibers and stabilized zirconia powder, forming the mixture into a refractory sheet having flexibility at room temperature, laminating the refractory sheet to form a multi-layer and firing the laminate.
