• Description: Molten fluoride salts are investigated as cooling media for molten salt and high temperature reactors. Structural materials of heat exchangers may be attacked at temperatures of about 700 C and the melt-alloy interaction provokes microstructure and composition changes of contact surface. Resulting interface is studied by means of laser ablation with inductively coupled plasma mass spectrometry (LA-ICP-MS). Laser ablation is used as a local solid-sampling method, which represents an alternative to routinely used methods such as electron probe microanalysis (EPMA) and scanning electron microscopy (SEM).
