MAX phases as candidates for Concentrated Solar Power receivers
New generation concentrated solar power (CSP) plants require new solar
receiver materials with selective optical properties and excellent corrosion
resistance against molten salts. MAX phases are promising materials for CSP
applications due to their optical properties and resistance to extreme
environments. Herein, we report a solar absorptance above or equal to 0.5 and a
thermal emittance of 0.17-0.31 between 600 and 1500 K for Cr2AlC, Ti2AlC, and
Ti3AlC2. These compositions were also exposed to solar salt corrosion at 600
{\deg}C for up to 4 weeks. Cr2AlC exhibited a superior corrosion resistance due
to the formation of a protective nanometric layer.Comment: 19 pages, 5 figures, 1 tabl
