The Ti₃SiC₂ MAX phase was synthesized by arc-melting process under three different processing times. We confirmed that the reaction between the TiCX phase and Ti-Si liquid phase is important for the synthesis of the Ti₃SiC₂ MAX phase. Results suggest that the Ti₃SiC₂ MAX phase decomposed when the arc-melting time was greater than 80s. Herein, we aim to determine the detailed parameters for the reported arc-melting process, which can provide useful insights on the synthesis of the Ti₃SiC₂ MAX phase by arc-melting process. Furthermore, we compared the electrical characteristics and densities of the three samples.
