1. A process for heating a material to be processed using an infrared lamp with a closed enveloping tube including an emission source joined with contacts for a power supply in the form of a carbon ribbon which, extending in a direction of the long axis of the enveloping tube, determines an irradiation length of the infrared lamp, wherein the carbon ribbon has a length which is greater than the irradiation length by at least a factor of 1.5, which permits a heating rate of at least 250°

  • C./second, the process comprising the step of;

    operating the infrared lamp such that its emission maximum lies with a wavelength in a range from 1.8 μ

    m to 2.9 μ

    m, and in that its power output reaches at least 15 Watts per cm3 of volume enclosed by the enveloping tube over the irradiation length.
