ZirCa-HoT: Validation of materials based on zirconium carbide for extreme thermal requirements in high temperature plants
Zirconium carbide (ZrC) is characterized by the combination of extremely high thermal stability (> 2000 °C) with very good electrical conductivity. It also has a very low vapor pressure at high temperatures. As a material, it is therefore ideally suited for use as heating element for high-temperature processes under vacuum. Up to now, the production of dense zirconium carbide was only possible at very high costs, so that an economic production was not competitive.
The aim of the project is the development of a stable production process for zirconium carbide heating elements in small series.
In addition, a test heating system is to be set up with which the operating behavior of the zirconium carbide heating elements can be investigated in order to obtain practicerelevant data on the aging behavior of zirconium carbide and to define the application framework for these ceramic heating elements.
