Abstract
Liquid tin is considered to be a promising plasma-facing material used in intra-chamber components of a stationary fusion reactor. Since corrosion in liquid tin is largely due to dissolution of solid metals in liquid tin, the solubility and thermodynamic activity of the main components of the structural material are key parameters for understanding corrosion processes. The solubility of the transition metals Fe, Cr, Nb, Mo, and W in liquid tin has been theoretically calculated and the results obtained have been compared with the experimental data from the literature. The results of experiments on the compatibility of molybdenum with liquid tin at 1050°C are reported. The results obtained agree well with the computational estimate and provide an optimistic basis for continuing the investigations on a wider time basis under the conditions similar to those for in-chamber tokamak components.
期刊介绍：
Technical Physics Letters is a companion journal to Technical Physics and offers rapid publication of developments in theoretical and experimental physics with potential technological applications. Recent emphasis has included many papers on gas lasers and on lasing in semiconductors, as well as many reports on high Tc superconductivity. The excellent coverage of plasma physics seen in the parent journal, Technical Physics, is also present here with quick communication of developments in theoretical and experimental work in all fields with probable technical applications. Topics covered are basic and applied physics; plasma physics; solid state physics; physical electronics; accelerators; microwave electron devices; holography.
