    摘要: In one aspect, ceramic resistive heating elements are provided that comprise three or more electrically segregated conductive zones. In another aspect, ceramic heating elements are provided that comprise a plurality of conductive zones, wherein only a portion of the conductive zones pass current during use of the heating element. In a further aspect, heating elements of the invention can be readily modified to operate at a variety of voltages. The multiple conductive zones can provide extended heating element operating lifetimes.

    摘要: 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.
