摘要： An electric heating element is provided with a durable PTC resistance made at least partially of an iron-based alloy, exhibiting stable characteristics to a temperature of 1500 DEG C. and having a resistance/temperature characteristic curve which substantially increases in a linear manner within a temperature range between an ambient temperature and 1500 DEG C. and can be used for a temperature control. The PCT resistance is provided with an oxidation resistant metallization or is gas-tightly enveloped by a jacket (2, 3, 12), a space between the jacket (2, 3, 12) and the PCT resistance (1,13) being filled with a powder or granules (14) which remove an important gas amount from the space.
