The MAX Phase (including Ti3SiC2, T2AlC and others. A new kind of machinable ceramic materials has been gaining a lot of attention.
More than fifty types of ternary carbides, nitrides are included in this material. M stands for a transitional metal element. A denotes the main group element. X refers to carbon and nitrogen. It is possible to express the fundamental chemical formula M (n+1) AXn. The most studied element of this group, Ti3SiC2, can be found in the form M (n+ 1) AXn.
Ti3SiC2 (Ti3SiC2) was created in Drexel University by Professor Barsoum using hot pressing. He found it to be extremely efficient. The unique structure of these nano-layered crystals gives them the ability to self-lubricate, resist abrasion, and conduct electricity. They can be used widely as high temperature structural materials, electrode brush material, chemical anticorrosion and high-temperature heater materials. In Japan, Europe, China, and China, extensive research has been done on these materials since 1996.
An excellent example is Titanium silicon caride (Ti3SiC2), which has been used in MAX materials. High-temperature plasticity and good thermal and electrical conductor properties make titanium silicon carbide a great choice for MAX materials. This ceramic-like material has high-temperature and oxidation resistance. You can describe it as beautiful cross-border mixture of metals and ceramics. China currently has several units that can mass-produce and then invest in this material in their industrial applications.
The MAX phase ceramics possess the outstanding properties of both metal and ceramic materials. These materials can be used as electrode brushes materials, high temperature structural materials, high heat materials, chemical anticorrosion materials and high-temperature heating material.
This is a brand new type of ternary-layered ceramic material made from titanium aluminum carbide. Materials scientists and physicists have been very interested in it.
It belongs to the hexagonal system, and shares both the properties of ceramics and metals. It is basically the same as other metals in terms of electrical conductivity and temperature resistance, but it also exhibits excellent elastic modulus and mechanical properties at high temperatures similar to ceramics. You will also find it resistant to heat shock and chemical damage.
Due to their unusual structure and potential application in the field spintronics they have been much in demand. One example is the huge magnetoresistance effect that layered magnetic materials have had on magnetic recording and data storage. Researchers are working hard to discover new magnetic materials for different applications. MAX Phase is a kind of nano-layered compound made up of transition metals with hexagonal lattice structures. The molecular formula for Mn+1AXn is (where A is the predominant element of the main groups 13-15 and M is the metal, M is the most common transition group), 1.
Analyzing the MAX phase lattice’s bonding characteristics, we can see that there is a significant overlap in electron clouds between M atoms and X atoms. The strong ionic or covalent bonds are determined by the overlap. Weak electron cloud overlaps between M atoms and A atoms indicates weak ionic or covalent bonds.
If a magnet element with a unique, nano-layered structure and high stability is added to the MAX Phase’s A site, then it can be used in spintronic device functional materials. However, it was generally assumed that Mn, Co, Ni and Fe with 3d electrons would exist at the M-atomic phase site. Therefore, a magnetic element was created to be located in A of the monoatomic two-dimensional layer of the MAX phases. It’s a major challenge.
Ningbo Institute of Materials, Advanced Energy Materials Engineering Laboratory, has recently adopted the alloy-controlled path to synthesis and introduced magnetic elements Fe / CO / Ni / mn into the A Phase of the MAX. V2SnC can exist in phase equilibrium in V-Sn -C with Sn and vanadium carbonide, according to theoretical analysis. If a magnetic element is added, V2 (AxSny), the C phase, can be in phase equilibrium the AxSny metal and AxSny alloy phase. This means that the VC1x and intermediate liquid AxSny become V2 or AxSny (C).
Fe and other magnet elements possess a greater chemical affinity for Sn than the V ternary V Sn-C system. Therefore, it is preferred over V metal combinations to create Fe-Sn alloy. The Fe-Sn combination will allow the nucleation and formation of VC1x at low temperatures and suppress the formation of V-Sn competitive phases. By using the peritectic process, both the liquid AxSny-x alloy and the nanocrystals of VC1x form the C phase V2 (AxSn1x). Further, all the magnetic elements were found in the A site monoatomic layer using the scanning electron microscope Z/contrast imaging technology as well as atomic resolution energy spectrum analyze technology. Furthermore, only one element of vanadium is present at the M-site. For the expansion of MAX’s function, it will not be difficult to imagine a magnetic component with an outer layer d electrons at its A site.
As a result of the advances in research and breakthroughs in preparation technology, MAX phase material’s “family” is growing and their performance are continually being improved. MAX Phase materials are poised to boom with high-end equipment and miniaturization.
