The invention relates to a heating element (7) for a furnace, which heating element comprises a sapphire glass tube (8) for receiving a heating coil (17) inside the sapphire glass tube (8). The sapphire glass tube (8) is gas-tightly connected to a borosilicate tube (14) and also to a quartz glass tube (15). The electrical connections at the ends lead through in a gas-tightly compressed manner. According to the invention, the tube element is made of sapphire (8) and is gas-tightly joined by transition glasses and glass solder to compensate for the different coefficients of thermal expansion. The joined elements (14, 15) are located outside the firing chamber (2) so that they ensure operational reliability in the case of a thermal effect of up to 500 C. Furthermore, for firing/sintering the ceramic element (4) with shortwave infrared radiation in the range of from 0.8 m to 2.5 m, the heating element (7) has stable optical, electrical and mechanical properties and thus high-quality, permanently uniform firing and sintering results are ensured with significantly shortened firing-sintering times. No changes to the surface of the heating elements (7) occur which are caused by chemical influences or evaporations from the fired-sintered elements. No contamination of the sintered objects and the firing chamber occurs which is caused by the heating element (7). The heating element (7) can be used at an operating temperature up to 1900 C. and thus ensures use over long uptimes.
