Max Phase Materials: Advancements in Materials Engineering

MAX materials and MXene materials are new two-dimensional materials that have attracted much attention lately, with excellent physical, chemical, and mechanical properties, and possess shown broad application prospects in numerous fields. This is an in depth overview of the properties, applications, and development trends of MAX and MXene materials.

Precisely What is MAX material?

MAX phase material is really a layered carbon nitride inorganic non-metallic material consisting of M, A, X elements on the periodic table, collectively called “MAX phase”. M represents transition metal elements, such as titanium, zirconium, hafnium, etc., A represents the primary group elements, such as aluminum, silicon, germanium, etc., X represents carbon or nitrogen. MAX-phase materials, each atomic layer is composed of M, A, X, three of the aspects of the alternating composition arrangement, with hexagonal lattice structure. Because of 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 as well as other fields.

Properties of MAX material

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