Product Description
Titanium Aluminum Carbide (Ti₃AlC₂) is a highly regarded member of the MAX phase family, offering a rare combination of metallic and ceramic properties. With its nanolaminated hexagonal crystal structure, Ti₃AlC₂ provides outstanding electrical and thermal conductivity, high fracture toughness, and oxidation resistance, while also being machinable at room temperature.
As a ternary carbide, it is frequently used as a precursor material for MXenes (specifically Ti₃C₂Tx), enabling high-performance applications in energy storage, electronics, and electrochemical catalysis. Its unique structure allows for plastic deformation at high temperatures, making it a versatile material in both research and industry.
