Abstract
A heating element comprising a three dimensional substrate having coating-containing electrically conductive tin oxide on at least a portion of all three dimensions thereof, the coated substrate being adapted and structured to provide heat in response to the presence of one or more electrical and/or magnetic fields.
Claims28
A resistance heating element comprising an inorganic three dimensional substrate having at least partially shielded surfaces associated with said substrate and having a dopant containing electrically conductive tin oxide coating on at least a portion of said at least partially shielded surfaces and all three dimensions thereof, said coated substrate being adapted and structured to provide heat in response to the presence of one or more electrical currents therein, said dopant being present in said coating in an amount effective to control the heating response of said coating in said element.
A heating element comprising an inorganic three dimensional substrate having at least partially shielded surfaces associated with said substrate and having a dopant containing electrically conductive tin oxide coating on at least a portion of said at least partially shielded surfaces and all three dimensions thereof, said coated substrate being adapted and structured to provide heat in response to the presence of one or more force fields therein, said force fields being selected from the group consisting of electrical fields, magnetic fields and combinations thereof, said dopant being present in said coating in an amount effective to control the heating response of said coating in said element.
