论文摘要
新一代浓缩太阳能（CSP）需要具有选择性光学特性和对熔融盐的极佳耐腐蚀性的新太阳接收器材料。由于其光学特性和对热冲击的抵抗力，最大相是CSP应用的有前途的材料。在此，我们报告了太阳能吸收>/= 0.5，CR2ALC，TI2ALC和TI3ALC2的600至1500 K之间的热发射率为0.17-0.31。这些成分还暴露于在600°C下最多4周的太阳盐腐蚀。 CR2ALC由于保护性纳米层的形成而表现出优质的耐腐蚀性。
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 thermal shocks. Herein, we report a solar absorptance >/= 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°C for up to 4 weeks. Cr2AlC exhibited superior corrosion resistance due to the formation of a protective nanometric layer.
