MAX Phase Powders

What are MAX Phase Powders?

MAX phases are a unique family of layered ternary carbides and nitrides with the general formula Mₙ₊₁AXₙ, where M is an early transition metal, A is an element from groups 13–16, and X is carbon or nitrogen. In powder form, MAX phases exhibit a rare combination of metallic and ceramic properties, making them versatile materials for advanced engineering applications.

Key Features

MAX phase powders uniquely combine metallic conductivity and machinability with ceramic‑like thermal stability and oxidation resistance. Their layered crystal structure enables selective etching of the “A” element, making them essential precursors for producing MXenes. With high damage tolerance and exceptional resistance to thermal shock, these materials deliver reliable performance even in extreme environments, bridging the gap between metals and ceramics in advanced applications.

Applications

These powders are widely used in structural ceramics, where their ability to withstand high temperatures and resist wear ensures long‑lasting performance. In aerospace and energy systems, they serve as protective coatings that guard against oxidation and corrosion. Their metallic conductivity also makes them suitable for electrical contacts in advanced electronics. Beyond these uses, MAX phases play a critical role as parent materials for MXenes, enabling the development of cutting‑edge two‑dimensional nanomaterials with diverse functionalities.
