SiC/SiC composite heater for IFMIF

As the part of Japan/EU Broader Approach (BA) program for fusion, International Fusion Materials Irradiation Facility/Engineering Validation and Engineering Design Activities (IFMIF/EVEDA) project is on-going. Where, High Flux Test Module (HFTM) design aiming up to 1000 °C has been intensively investigated. Innovative SiC/SiC heater is currently potential and promising option. The weak temperature dependence of the SiC/SiC up to 1000 °C was interpreted to suggest the important role of grain boundaries and fiber–matrix interphase. To control the heater properties, variety of fabrication conditions, mainly on SiC nano-powders and green-sheet, were selected and tested. The heater performance was reasonably controlled and the results of heater performance and underlying microstructure behavior are provided.
