Carbon/Fluoride Composite for Advanced Solar Dynamic Receiver

The application of composite materials, ceramics or carbon materials with molten salts, to latent thermal energy storage in solar dynamic receiver is one of the possibility to overcome various problems due to physical properties of molten salts. The authors have proposed and successfully developed some composites of silicon carbide-and fluorides, e.g. SiC/LiF, SiC/LiF-CaF/sub 2/, SiC/MgF/sub 2/. For developing further sophisticated and advanced receiver, on the other hand, an attempt at developing carbon composite with molten fluorides has also been made. In the present paper, materials production process and preliminary results of thermal analysis are described. The present paper also describes high temperature He-Xe experimental systems for receiver component evaluation which was currently installed in Electrotechnical Laboratory.
