Abstract: An apparatus for generating infrared radiation is provided including an electrical heating element that is able to withstand very high, continuous-use temperatures, surrounding or surrounded by a non-conductive material containing dopants of refractory metal oxides, rare earth oxides, or combinations of both. The material may be shaped about the heating element so that the infrared radiation emissions may be focused and/or directed in a desired manner.
