Max Phase Materials: A Game-Changer for Electronics Cooling

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 also have shown broad application prospects in numerous fields. The following is an in depth introduction to 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 comprising M, A, X elements around the periodic table, collectively referred to 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 aspects of the alternating composition arrangement, with hexagonal lattice structure. Because of the electrical conductivity of metal and high strength, high-temperature resistance and corrosion resistance of structural ceramics, these are commonly used in high-temperature structural materials, high-temperature antioxidant coatings, high-temperature lubricants, electromagnetic shielding along with other fields.
