Abstract:

Article Preview

The Nb2AlC powders 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 1600–1650°C 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 improved crystallization at 1610°C.And the SEM photographs show that the products are layered morphology.The reaction mechanism of Nb2AlC synthesis was also studied.
