Max Phase Materials: The Strength of Ceramics, the Flexibility of Metals

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

Precisely What is MAX material?

MAX phase material is actually a layered carbon nitride inorganic non-metallic material composed of M, A, X elements around the periodic table, collectively known as “MAX phase”. M represents transition metal elements, like titanium, zirconium, hafnium, etc., A represents the key group elements, such as aluminum, silicon, germanium, etc., X represents carbon or nitrogen. MAX-phase materials, each atomic layer is made up of M, A, X, three of the elements of the alternating composition arrangement, with hexagonal lattice structure. Because of their electrical conductivity of metal and high strength, high-temperature resistance and corrosion resistance of structural ceramics, these are popular in high-temperature structural materials, high-temperature antioxidant coatings, high-temperature lubricants, electromagnetic shielding along with other fields.
