Description
Titanium Aluminum Carbide (Ti₂AlC) MAX Phase Micron Powder
Average Particle Size (APS): -325 Mesh
Purity: 99+%
Product Description
Titanium Aluminum Carbide (Ti₂AlC) is a member of the MAX phase family of nanolaminated ternary carbides, offering a unique blend of metallic and ceramic properties. With a hexagonal crystal structure and fine particle morphology, Ti₂AlC exhibits excellent electrical and thermal conductivity, mechanical resilience, and machinability — even at room temperature.
Its nanolayered structure gives it high oxidation resistance, thermal shock resistance, and damage tolerance. These features make Ti₂AlC especially suitable for demanding applications such as MXene production, high-temperature coatings, conductive ceramics, and electrochemical devices.
