英文摘要	The thermal decomposition of Ti₃SiC₂ in vacuum furnace up to 1500 ℃ has been investigated. The results show that the mild decomposition of Ti₃SiC₂ commences at 1300 ℃ and the higher the holding temperature, the larger the volatilization of Si atoms. The Ti₃SiC₂ decomposition occurs simultaneously on the surface and in the bulk. Four phases coexist at 1400 ℃ and 1450 ℃ and the Ti₅Si₃C_x phase appears in the bulk and/or surface. Diffusion distance, rate, and volatilization of Si contribute to the porous structure and the presence of Ti₅Si₃C_x. The evolution of furnace pressure reflects the decomposition kinetics of Ti₃SiC₂.
