with common granite rock and a pelletized iron ore. Results indicate that the long-term stability of iron-ore pellets in binary mixtures of potassium and sodium nitrates is superior to granite rock-salt mixtures and salt systems without solid media. Corrosion of the Inconel 600 vessels was observed.
