Abstract:
A method of making a ceramic heater comprising the steps of:a) making a ceramic slurry;b) combining said ceramic slurry with a binder component to form a slip, said slip consisting essentially of the following constituents: Al.sub.3, O.sub.3, H.sub.2 O, PVA, Glycerol, SiO.sub.2, CaCO.sub.3, PEG 3350, PEG 8000, Darvan 821A, MgO, and ZnO;c) depositing said slip onto a carrier film at a controlled thickness such that a deposited slip is formed;d) heat curing said deposited slip to form a cured slip ribbon;e) applying a platinum paste onto said ribbon in a specific pattern, said paste forming a platinum resistor element on said ribbon;f) applying said ribbon with said platinum resistor element onto an alumina rod; and,g) heating said rod with said ribbon and said platinum resistor element thereon, whereby said ribbon is sintered to said rod and said platinum resistor element is sintered and bonded to said ribbon.
