Chromium Aluminum Boride (Cr₂AlB₂) MAX Phase Powder (99+%, 200 mesh)

Description

Chromium Aluminum Boride (Cr₂AlB₂) MAX Phase Powder (99+%, 200 mesh)

Chromium Aluminum Boride (Cr₂AlB₂) belongs to the family of MAX phase ceramics, a unique class of layered ternary carbides and borides known for their hybrid metallic and ceramic properties. With a purity of 99+% and particle size of 200 mesh, this dark gray powder combines metal-like electrical and thermal conductivity with ceramic-like hardness, oxidation resistance, and high-temperature stability.

The crystal structure of Cr₂AlB₂ consists of alternating layers of transition metal (Cr), aluminum (Al), and boron (B), which gives it excellent damage tolerance, high stiffness, and wear resistance while still maintaining machinability superior to conventional ceramics. This makes Cr₂AlB₂ a highly versatile material for demanding industrial, aerospace, and energy-related applications.
