摘要:
The invention provides new ceramic resistive heating elements and new methods for manufacturing ceramic resistive heating elements wherein the heating element body comprises two or more regions of differing resistivity, and wherein the heating elements are open face. Heating elements such as igniters and glow plugs also are provided obtainable from fabrication methods of the invention.
摘要:
The present invention relates a ceramic igniter comprising:a) a pair of electrically conductive portions, each portion having a first end,b) a hot zone disposed between and in electrical connection with each of the first ends of the electrically conductive portions, the hot zone having an electrical path length of less than 0.5 cm, andc) an electrically non-conductive heat sink material contacting the hot zone.
