Hexagonal layered boride ceramic h-MAB material and preparation method thereof
The invention relates to a hexagonal layered boride ceramic h-MAB material and a preparation method thereof, the molecular formula of the h-MAB phase material is represented as Mn + 1ABn or (MB) 2zAx (MB2) y, M is selected from any one of IIIB, IVB, VB, VIB, VIIB and VIIIB group elements, A is selected from any one of IIIA, IVA, VBA, VIA and VIIA elements, and B is a boron element. And the h-MAB phase material has a hexagonal crystal system structure. Wherein the transition metal boride unit MB and the A layer are alternately stacked. The preparation method comprises the following steps: uniformly mixing M powder, A powder and B powder according to a certain molar ratio, wrapping the uniformly mixed powder by using molybdenum foil as a protective layer on the mixture, putting into a quartz tube, and putting into a high-temperature tube furnace for reaction. The method is simple and effective, raw materials are easy to obtain and low in price, and the method has important industrial application prospects. The invention also discloses element spaces and chemical components which may exist in the h-MAB phase. The invention further discloses possible application of the h-MAB phase material, and the h-MAB phase material is good in mechanical property, good in conductivity, high in hardness and the like.
