Synthesis of Ti3AlC2/Al2O3 nanopowders by mechano-chemical reaction

Effects of ball milling sequences on the in-situ reactive synthesis of the Ti2SC MAX phase

“…As discussed before [16], a mechanically induced combustion synthesis (MSR) mechanism was responsible for Ti 2 SC formation. The MSR mechanism has also been reported to govern the synthesis of several MAX phases and their composites [19][20][21]. The overall reaction between Ti, FeS 2 , and C could be considered as follows:…”

Synthesis and Regeneration of A MXene-Based Pollutant Adsorbent by Mechanochemical Methods

“…High energy ball milling was utilized to prepare Ti 3 C 2 T x MXene from Ti 3 AlC 2 MAX phase (which was synthetized from TiO 2 , Al, and graphite by ball milling according to the procedure of Zhu et al [22]) utilizing a MC etching method with HF. Specifically, 1 g MAX phase powder was exfoliated in solely 20 mL hydrofluoric acid (40% solution) by ball milling.…”

“…Ti 3 AlC 2 MAX phase was synthetized according to a modified version of the method described by Zhu et al [22]. Titanium oxide, aluminum powder, and graphite were used to prepare Ti 3 AlC 2 by the reaction:3 TiO 2 + 5 Al + 2 C → Ti 3 AlC 2 + 2Al 2 O 3 …”

“…; A is an A-group element, e.g., Al or Si; and X is C or N) [20,21] (Figure 1). MAX phase carbides can be easily MC synthetized by high energy milling of transition metal dioxide, aluminum, and carbon [22]. Etching of Al atoms to release bidimensional carbide layers is realized by mixing the MAX phase with concentrated hydrofluoric acid for long time (typically, 24 h), and the etching method is responsible for the formation of different functional groups (e.g., ‒F, ‒OH, =O, etc.)…”

Mechanochemical synthesis mechanism of Ti 3 AlC 2 MAX phase from elemental powders of Ti, Al and C

“…84 Jin et al [10] used ball milling to synthesize Ti 3 SiC 2 MAX 85 phases. Yang et al [11], Shi et al [12], Zhu et al [13] and Sadeghi 86 et al [14] synthesized successfully MAX phase in Ti-Al …”
