AbstractIn the present study it was possible to provide evidence that ZrC ceramics – regarding their electrical‐mechanical and thermal properties – are an attractive substitute for tungsten and molybdenum in the field of refractory materials and heating elements. For this purpose, the heating behavior of ZrC materials was investigated in a specific test stand under high vacuum conditions (10−6 mbar) at temperatures above 2000 °C. In addition, the applicability of ZrC as an electrical heating element was investigated in terms of geometric design and long‐term behavior. Examinations after the heating tests did not reveal any significant changes in the material.
