Max materials

MAX materials (including Ti3SiC2, Ti2AlC, etc.) are a new type of machinable ceramic materials that have received much attention.

MAX materials include more than fifty kinds of ternary carbides or nitrides. M represents a transition metal element; A represents a main group element; X represents carbon or nitrogen. The basic chemical formula can be expressed as M(n+1)AXn, of which Ti3SiC2 is the most widely studied. Ti3SiC2 was synthesized by Professor Barsoum's research group of Drexel University in 1996 by hot pressing method, and found its excellent performance. Due to the unique nano-layered crystal structure, these materials have the properties of self-lubrication, high toughness, and electrical conductivity. Such materials can be widely used as high-temperature structural materials, electrode brush materials, chemical anti-corrosion materials and high-temperature heating materials. After 1996, research related to such materials has been widely carried out in Japan, Europe and China.
