Description: MAX phases have been produced for the first time via an exchange reaction between the M-element oxide and Al leading to an M–Al–C–Al₂O₃ composite in the V–Al–C, Cr–Al–C, Nb–Al–C and Ta–Al–C systems in addition to the previously known Ti–Al–C system. The reduction reaction was first investigated by forming the binary M–X carbide and then proven to be generic across all M–Al–C systems with the production of the M₂AlC phase in each case. The work was extended to the other M₃AlC₂ and M₄AlC₃ phases in the respective systems, and was successful in 4 of the 5 cases with moderate yield.
