Chromium Aluminum Carbide (Cr₂AlC) MAX Phase Micron Powder
Purity: 99%, Size: -400 mesh
Chromium Aluminum Carbide is a nanolaminated ternary compound representing the unique characteristics of the MAX phase family. Its crystal structure consists of strong covalent Cr-C layers alternated with aluminum atomic layers, creating a distinctive metal-ceramic dual behavior. Cr₂AlC demonstrates excellent chemical stability in oxidizing environments, where chromium and aluminum collaboratively form protective surface oxide layers. Unlike conventional brittle ceramics, its layered structure enables energy absorption through delamination and kink mechanisms, providing high damage tolerance and allowing machining with standard tools.
