Ti-Al-C MAX phases by aluminothermic reduction process

A new approach to synthesis of Ti 2 AlC-Ti 3 AlC 2 /Al 2 O 3 compounds is developed based on thermite reaction in the TiO 2 -Al-C system. The effect of Al excess is also discussed. XRD analysis has proved that this parameter can be used to improve the product purity, i.e., the amount of TiC in the f...

Zusammenfassung:A new approach to synthesis of Ti 2 AlC-Ti 3 AlC 2 /Al 2 O 3 compounds is developed based on thermite reaction in the TiO 2 -Al-C system. The effect of Al excess is also discussed. XRD analysis has proved that this parameter can be used to improve the product purity, i.e., the amount of TiC in the final product. It has also been shown that, with increasing Al excess, the composition of a major MAX phase undergoes a change from Ti 2 AlC to Ti 3 AlC 2 .
