Molten metal chloride salts are promising candidates for advanced heat transfer fluids in generation IV nuclear reactors and beyond. However, research on the magnetic properties of suspended metallic nanoparticles at elevated temperatures is scarce, there have been no attempts to develop a high-temperature, molten salt based ferrofluid. Such ferrofluid would enable situ manipulation both physical thermal fluid via an external field. This study examines ferrofluids comprised cobalt dispersed salts. High-temperature magnetometry magneto-thermogalvometric measurements were conducted evaluate characteristics Further analysis was through combination microscopy, spectroscopy, solubility tests, diffraction measurements. The exhibited notable degree chemical stability sustained magnetism from 25 800 °C when NaCl–MgCl2 KCl–ZnCl2 mixtures.
