Synthesis of Ti3SiC2SiC and TiSi2SiC composites using displacement reactions in the TiSiC system

Phase reactions associated with the formation of Ti3SiC2 from TiC/Si powders

“…Ti 3 SiC 2 has been reported to form in TiC/Si powder mixtures, in spite of the relatively low reactivity of TiC, and TiSi 2 has been suggested to be an intermediate phase [22][23][24][25]. Li et al [26] postulated that the dominant intermediate phase would be Ti 5 Si 3 and Hwang et al [27] reported a solid state reaction between TiC 0.67 /Si powders without intermediate phases.…”

Reaction in Ti3SiC2 powder synthesis from a Ti–Si–TiC powder mixture

“…It was firstly synthesized via chemical reaction in 1967 [1], and then by CVD in 1987 [2]. In recent years, different starting powder mixtures, including Ti-Si-C [3][4][5][6][7][8][9][10][11][12][13], Ti-SiC-C [14], as well as Ti-Si-TiC [15][16][17] were used as starting materials, and various methods, such as arc-melting [3], HIP or SHS-HIP [4][5][6][7]14], reactive sintering [8][9][10][11][12][13], pulse discharge sintering [15][16][17] have been employed for the fabrication of bulk Ti 3 SiC 2 . In all cases, it is difficult to synthesize single phase bulk Ti 3 SiC 2 material.…”

Microstructure and properties of Ti3SiC2/SiC nanocomposites fabricated by spark plasma sintering

“…Therefore, fabrication of Ti 3 SiC 2 /SiC composites has attracted much attention and it has been verified that Ti 3 SiC 2 /SiC composites exhibit improved hardness, wear, and oxidation resistance [3,[7][8][9][10]. Most of the attempts to synthesize Ti 3 SiC 2 /SiC composites have been carried out by HP or HIP methods.…”
