Max Phase Materials: Redefining the Landscape of Metallurgy

MAX materials and MXene materials are new two-dimensional materials which have attracted much attention in recent years, with excellent physical, chemical, and mechanical properties, and possess shown broad application prospects in lots of fields. The following is a detailed overview of the properties, applications, and development trends of MAX and MXene materials.

What is MAX material?

MAX phase material is a layered carbon nitride inorganic non-metallic material comprising M, A, X elements in the periodic table, collectively called “MAX phase”. M represents transition metal elements, like titanium, zirconium, hafnium, etc., A represents the key group elements, including aluminum, silicon, germanium, etc., X represents carbon or nitrogen. MAX-phase materials, each atomic layer is composed of M, A, X, the three components of the alternating composition arrangement, with hexagonal lattice structure. Due to their electrical conductivity of metal and strength, high-temperature resistance and corrosion resistance of structural ceramics, they may be popular in high-temperature structural materials, high-temperature antioxidant coatings, high-temperature lubricants, electromagnetic shielding and other fields.

Properties of MAX material

MAX material is really a new type of layered carbon nitride inorganic non-metallic material with all the conductive and thermal conductive qualities of metal, comprising three elements with all the molecular formula of Mn 1AXn (n=1, 2 or 3), where M means the transition metal, A means the main-group elements, and X means the aspects of C or N. The MXene material is a graphene-like structure obtained through the MAX phase treatment with two-dimensional transition metal carbides, nitrides, or carbon-nitrides. MAXenes and MXenes are novel two-dimensional nanomaterials made from carbon, nitrogen, oxygen, and halogens.
