· Zr2AlC

Zr₂AlC is a MAX phase ceramic—a ternary layered compound combining the stiffness of ceramics with metallic electrical and thermal conductivity properties. This material remains largely in the research and development stage, but represents a promising class for high-temperature structural applications where traditional ceramics are too brittle or where electrical/thermal transport is required alongside mechanical strength.
