^{Product Overview}

The MAX phase is A ternary layered ceramic material, where M is a transition metal element, A is mainly a third and fourth main group element, and X is carbon or nitrogen. The crystal unit arrangement of this material is hexagonal structure, and the space point group is P63/mmc, where the M atomic layer and the A atomic layer are alternately arranged to form a layered structure similar to the close-packed hexagonal structure, and the X atom is filled in the gap position of the octahedron. Where M is the pre-transition metal element, A is the main group element, X is the carbon or nitrogen element, n= 1,2,3, so it is referred to as the MAX phase. When n=1, it is 211 phases, such as Ti2AlC and Ti2SiC; When n=2, it is 312 phases, such as Ti3SiC2 and Ti3AlC2; When n=3, it is called 413 phase, such as Ti4AlN3. High entropy is a material design concept developed from high entropy alloys, first proposed in 2004. MAX phase materials usually have similar physical and chemical properties due to their M, A and X position elements located in the same family or adjacent positions, and have adjustable composition. High entropy of MAX phase materials can be made by solid solution of 3 to 5 elements at M or A position in the same system. In addition, the slow diffusion effect caused by high entropy will also affect the mechanical properties of MAX phase high entropy materials. The main preparation methods of high entropy MAX phase ceramics are hot pressing sintering, discharge plasma sintering, self-propagating high temperature synthesis, hot isostatic pressing and mechanical alloying.

^{Product Features}

High-entropy structure: High-entropy MAX phase ceramics are characterized by a high-entropy structure, which means that it is composed of multiple elements mixed in equal or near-equal atomic proportions. This high entropy structure gives it high hardness, oxidation resistance and high temperature stability.

Nano-layered structure: Similar to traditional MAX phase ceramics, high-entropy MAX phase ceramics also have a nano-layered structure. This structure consists of alternating layers of metal and carbon (or nitrogen), giving the material good mechanical properties and machinability.

^{Application Fields}

Aerospace field: High entropy MAX phase ceramics have excellent high temperature stability, oxidation resistance and ablative resistance, and can be used to manufacture aircraft engine hot end components, rocket nozzles and so on.

Chemical field: The corrosion resistance of high-entropy MAX phase ceramics makes it suitable for chemical equipment, such as pipes, valves, pumps, etc.

Electronic field: Some high-entropy MAX phase ceramics have good electrical and thermal conductivity, and can be used for electronic packaging and heat dissipation materials.

Nuclear energy field: high entropy MAX phase ceramics have good stability under high temperature and irradiation environment, and can be used as structural materials and coatings in the nuclear energy field
