Preparation of Ti3SiC2 powders by the molten salt method

Ti3SiC2 powders were successfully obtained by the molten salt method using NaCl as the flux. The influences of synthetic temperatures and flux/powders weight ratio. on the phase and morphology of Ti3SiC2 powders were investigated. The results indicated that the synthetic temperature of Ti3SiC2 was about 150 degrees C lower than that reported by other methods. The Ti3SiC2 powders obtained by the molten salt method at 1200 degrees C were uniform and the particle size was about 1-2 mu m. The content of Ti3SiC2 increased as flux/powders ratio increased to 1:1 while the further increment of the ratio made the content decreases obviously. (C) 2013 Elsevier B.V. All rights reserved.
