Abstract: MAX phase materials exhibit unique properties that combine the performances of metals and ceramics. They offer great potential for concentrating solar-thermal power (CSP) applications. New structural materials with superior creep resistance are sought to achieve a design life of >30 years for Gen3 CSP solar receivers. Ti3SiC2 and Ti3AlC2 MAX phase materials are studied under a project sponsored by SETO. Dense disks and short-length tubes of MAX phase were prepared by field assisted sintering technology (FAST) and reactive infiltration processes and characterized. Details of fabrication approaches and characterization methods will be discussed.
