Ti3SiC2compound was synthesized from the starting powder mixtures of 3Ti/1.2Si/2C/xAl (x=0, 0.1, 0.2, 0.3) by using arc melting method. The effect of Al on the Ti3SiC2formation was studied. X-ray diffraction and scanning electron microscopy were used to characterize the synthesized materials. It was found that the addition of Al increased the purity of Ti3SiC2. Whenx=0.2, Ti3SiC2content in the final product reached 67% after being ball milled for 24 hours. However, excessive Al reduced the content of Ti3SiC2. In addition, the density of the final product decreased with increasing of Al content. It was revealed that addition of Al in the starting powders can increase the final product purity.
