The conductivity of metals is excellent, although they make it easy to conduct electricity. Do you think it is possible to combine the positives of ceramics, metals and other materials?
Scientists found an interesting class of layered ceramic materials that had special functions. Their three-element composition, M,A, and X, on the periodic list of elements was collectively called the “MAX phases”. This unique structure, which has a nano-layered crystal, allows the material to display the characteristics of both ceramics as well as ceramics. These materials possess almost every excellent property that is known. However, technical limitations in the preparation of such materials and other issues have limited their acceptance and application.
Luoyang Tongrun’s research team has developed a novel method to prepare MAX phase layers of ceramic materials. The group also created a range of new MAXphase materials — Titanium Aluminum Carbide. The chemical formulas for these materials are Ti3AlC2 or Ti2AlC. Their high quality opens new doors in terms of both research as well and their application. This material could also be useful in superconductivity, nuclear energy storage, flexible LCD, and superconductivity.
MAX phase is titanium aluminum carbide. It’s artificially synthesized. MAX may be similar to graphene.
They both are multilayered structures. It is easy to magnify graphene many billions more times and see the same arrangement of carbon atoms. What is different about the MAX phase? It has a M6X-octahedron, densely packed, and an A atomic.
Structure determines performance. MAX Phase’s nano-layered crystal structure gives it both the exceptional properties of ceramics and metals. These properties are what allow for the MAX phase to be useful in many other fields. Related research into this type of material continued in Japan (Europe, China) and Europe (China).
These materials are HTML3AlC2. HTML2AlC. It was common for the raw materials to have been combined in the past (M, A, or X).
Do you know what Du Jun’s Advanced Energy Materials Engineering Laboratory Team did?
Du Jun said, “We’ve developed a new method of replacing A-site sites atoms. To put it simply, first we create the’skeleton.’ This is made up of two materials, M, and X. After that, some method is used to produce the atom. By replacing the lattice spot precisely, we can get the A atom of our choice with some function.
This new method does not only outperform the traditional one in terms of ideas. It can also further be applied to MXene’s preparation in a more environmentally friendly fashion. “Traditional techniques generally contain highly toxic fluoride. Both sodium and potassium chlorineide are used in this process, as they are very common in real life. All of this is highly efficient and safe.
Innovative preparation methods and flexible control at the A-site are both expected to make MAX phase material titanium aluminum caride more versatile for traditional high-temperature structures to advanced functional uses.
“Like gold,” it’s well-known that tiny particles of the metal have greater catalytic power. This is because the MAX phases can precisely be replaced with gold atoms to make this material a powerful catalyst.
Du Jun’s research team is currently preparing a range of MAX phases materials ( Ti3AlC2, Ti2AlC). This new scenario has allowed for more research.
