Jesus Gonzalez : MAX phases: from synthesis to applications

Abstract

MAX phases have attracted a considerable attention in the last decades due to their unique combination of properties, bridging the gap between ceramics and metals. However, despite the potential of some compositions such as Ti₂AlC and Cr₂AlC to operate under aggressive environments, their transfer to applications is limited by three main factors: i) complexity of this large family of materials, ii) unavailability of highly pure commercial powders, and iii) extensive time to license products in strategic fields. In this work, reasons and potential solutions of these three points are discussed and correlated to the main properties of MAX phases and their synthesis routes. Emphasis is given to processing routes for developing different micro- and macro-structures and their relation with properties. In terms of applications, the latest results about the potential of MAX phases for Concentrated Solar Power (CSP) will be presented.
