The Nb2AlCpowders were synthesized by high temperature solid state reaction method,in which,the mixed powders of niobium(Nb),aluminum(Al),graphite(C)were used as raw materials in an atomic ratio of 2.0:1.1:1.0,respectively.And the heating temperature was adjusted in a range of 1550–1650℃ in order to investigate the effects of different preparing conditions on the synthesis of Nb2AlC.The phase composition and morphology of the products were analyzed by X-ray powder diffraction(XRD),scanning electron microscopy(SEM)respectively.The results indicated that all the XRD peaks can be indexed as Nb2AlC with good crystallization at 1650 ℃.And the SEM photographs show that the products are layered morphology.The reaction mechanism of Nb2AlC synthesis was also studied.
