Y3AlC
metal· Y3AlC
Y3AlC is a ternary ceramic compound belonging to the MAX phase family—layered carbides combining metallic and ceramic properties. This material exhibits a unique combination of high stiffness and low density, making it relevant for structural applications requiring lightweight performance. Y3AlC remains primarily a research and development material; its industrial adoption is limited, but it represents a promising class of compounds for high-temperature structural components and advanced aerospace applications where conventional ceramics or metals fall short.
