Overview of  Max phase material :

Max-phase materials are a new type of machinable ceramic materials that have received extensive attention. Due to the metal-like bonding properties of the Max phase, it has the function of conducting electricity and heat. Most MAX phase materials have good electrical and thermal conductivity. This also has to do with electronic structure.

MAX phase (including Ti3SiC2, Ti2AlC, etc.) is a new type of machinable ceramic material that has attracted much attention.

Applications of Max phase materials:

Max-phase materials are widely used in high-temperature structural materials, electrode brush materials, chemical anti-corrosion materials and high-temperature heating materials.

FAQ:

Q1:

What is Max phase material? 

Re：MAX phase materials refer to A class of nano-layered compounds with hexagonal crystal structures, which are mainly composed of M, A, and X elements in the periodic table. Where M represents the transition metal element, A represents the main group element, and X represents carbon or nitrogen. The crystal structure of these materials consists of transition metal carbonitride layers (MX layers) and A-site atomic layers, which are alternately stacked to combine the characteristics of metal and ceramic materials.

Q2:

What are the uses of MAX phase materials? 

Re：Energy field: MAX phase materials have high electrical conductivity and excellent ion transport performance. In addition, it can also be used as a catalyst for catalytic reactions, such as oxygen reduction reactions, hydrogen precipitation reactions, etc., with good catalytic activity and stability.

Sensor field: MAX phase materials, such as gas sensors, optical sensors, etc., can also be used as sensor materials, which can achieve high sensitivity and high selectivity sensing performance.

Material science: MAX phase materials have the electrical and thermal conductivity properties of metals. Therefore, in the fields of high-temperature lubrication, oxidation-resistant coating, accident-tolerant nuclear materials, self-healing composites, and energy materials, MAX phase materials have also received wide attention.

Q3:

What are the advantages of MAX phase materials? 

Re：Excellent mechanical properties: MAX phase material has high hardness, superior bending strength, and good toughness so that it can withstand significant mechanical loads, and it is not easy to break under high strength and high load conditions.

Unique layered structure: MAX phase material is composed of an MX layer and an A atomic layer alternately stacked; this unique layered structure gives it good machinability and tribological properties and can be combined with many metals to improve the performance of metal materials.

Good electrical and thermal conductivity: MAX phase materials have the electrical and thermal conductivity properties of metals, which makes them have a wide range of application prospects in energy storage, electronic devices, and other fields.

Q4:

What are the types of MAX phase materials? 

Re：211 phase: This is the first class of MAX phase materials discovered and studied, and its general formula is M2AX, where M is A transition metal element (such as Ti, V, Cr, Nb, etc.), A is a significant group element (such as Al, Si, Ge, etc.), and X is C or N. Common 211 phase materials are Ti2AlC, Ti2AlN, V2AlC, and so on.

Phase 312: Its general formula is M3AX2, where M is A transition metal element (such as Ti, V, Cr, Ta, etc.), A is a significant group element (such as Al, Si, etc.), and X is C or N. Common 312-phase materials are Ti3AlC2, Ti3SiC2, Cr3AlC2, and so on.

Phase 413: Its general formula is M4AX3, where M is A transition metal element (such as Ti, Zr, Hf, etc.), A is a significant group element (such as Al, etc.), and X is C or N. Common 413 phase materials are Ti4AlN3, Zr4AlC3, and so on.

Q5:

Preparation method of MAX phase material? 

Re：High-temperature solid-liquid reaction method: This is a method proposed earlier by in situ hot pressing Ti, Al, and graphite three powders to prepare the MAX phase. The technique has the advantages of a short preparation period, simultaneous synthesis and densification, high purity, and good universality. It can be used to synthesize a variety of MAX-phase materials. In addition, the density of the sample can be changed by controlling the pressure so as to obtain the MAX phase porous body.

Chemical vapor deposition (CVD): This is a standard method for preparing thin film materials and can also be used to prepare MAX phase materials. In this method, gaseous reactants are introduced into the reaction chamber and chemically react on the substrate surface to generate MAX phase films.

Hot pressing sintering method: Hot pressing sintering is a method of bonding and diffusion between powder particles under high temperature and high pressure so as to obtain a dense sintered body. This method can also be used to prepare MAX phase materials and high-quality MAX phase block materials can be obtained by controlling temperature and pressure.
