  • Method of making a ceramic heater with platinum heating element
    Patent number: 6495808
    Abstract: A ceramic heater having an alumina rod, an alumina based ribbon sintered to the rod, and a platinum resistor element bonded to the ribbon. Additionally, a method of making a ceramic heater having the steps of making a ceramic slurry; combining the ceramic slurry with a binder component to form a slip; depositing the slip onto a carrier film at a controlled thickness such that a deposited slip is formed; heat curing the deposited slip to form a cured slip ribbon; applying a platinum paste onto the ribbon in a specific pattern, the paste forming a platinum resistor element on the ribbon; applying the ribbon with the platinum resistor element onto an alumina rod; and, heating the rod with the ribbon and the platinum resistor element thereon, whereby the ribbon is sintered to the rod and the platinum resistor element is sintered and bonded to the ribbon.
    Type: Grant
