In 2013, guo et al Formed ti3sic2 from elemental powders in molten nacl, reporting a synthesis temperature 150 °c lower than other methods [17] Reported on the creation of cr2aic under vacuum using molten salts at 1000 °c [18]. Moreover, applying a pressure of 150 mpa to the prepared samples and using the eutectic mixture of nacl‐kcl (molar ratio 1:1) instead of nacl also resulted in the higher formation of ti3sic2 max phase. In the present work, we have developed a new method for the synthesis of ti3 sic 2 max phase powder in air from elemental powders by following a route of molten salt shielded synthesis (ms 3)
The details of the method are mentioned elsewhere [22]. The results showed that the following parameters enabled the ti3sic2 powder with a purity of 99.0 wt% to be obtained Formed ti 3 sic 2 from elemental powders in molten nacl for a synthesis temperature between 1000 and 1300 °c hold for 2 h [18]. The ti5si3 silicide phase was found to play a crucial role in the formation of the ti3sic2 max phase using the mss method 1:1) instead of nacl also resulted in the higher formation of the ti3sic2 max phase. Titanium silicon carbide (ti3sic2) max phase powder was synthesized from elemental reactants using the molten salt synthesis (mss) method
The results showed that ti3sic2was not synthesized using carbon black as the carbon source in the starting materials because of the. In this work, the selected silicon source was an alsi85 alloy, characterized by eutectic and liquidus temperatures of 577 °c and 1335 °c, respectively [13].
