| Abstract Scope |
Molten chloride salts have been proposed as heat transfer fluids for high temperature systems such as nuclear reactors, concentrated solar power, and thermal energy storage because of their high temperature stability and heat transfer properties. However, few materials can withstand both molten chloride salt and supercritical CO2. For this reason, ultrahigh temperature ceramics (UHTCs) and refractory alloys are viewed as potential heat exchanger materials. Our goal was to test UHTCs and powder-metallurgy hot isostatically pressed (PM-HIP) refractory alloys in molten chloride salt. Pure UHTCs, blended UHTCs, and PM-HIP refractory metals were exposed to purified and unpurified KCl-MgCl₂ at 800℃. Samples were then characterized with SEM, EDS, and optical microscopy. This talk will discuss corrosion resistance of UHTCs and PM-HIP refractory alloys in molten chloride salts, along with discussion of manufacture of PM-HIP alloys using standard and non-standard techniques. |
