Title:
CERAMIC HEATING DEVICE
Document Type and Number:
WIPO Patent Application WO/2011/116239
Kind Code:
A3
Abstract:
New ceramic resistive igniter elements are provided that comprise one or more portions provided with one or more surface patterns to thereby modify the electrical pathway and, further, modify the resistance in the one or more portions. New methods for fabricating resistive igniter elements are also provided wherein one or more surface patterns are provided, for example post densification, wherein the surface pattern(s) modify the electrical pathway through the elements as compared with the electrical pathway prior to disposition of the surface pattern(s). In particular, one or more interruptions are provided in the electrical pathway of an element such that the electrical pathway is modified and, further the resistance through the element is modified.
