The ternary layered compound Max phase is a new type of ceramic functional material.
It is a hexagonal layered structure in micro structure, which consists of MX layer and a atom layer alternately arranged. These ceramics contain more than 60 kinds of ternary carbides or nitrides. M represents the metal element in the front of the transition family; a for the main family element; and X for the carbon or nitrogen element. Transition metal carbides and nitrides are known as mxones.
Mxenes are a kind of layered solid, such as Ti2AlC, Ti3AlC2 and Ta4AlC3, which are connected by selective etching of a max phase with metal conductivity of an element, connected by strong solid metal bonds, ion bonds and covalent bonds. The metal conductivity is terminated by mxones combined with hydroxyl and oxygen on the surface of transition metal carbide.
