A simple approach is presented to synthesise the high-purity MAX phase by the pressureless method. This method is featured by the short time in duration. The process is executed with a high heating rate (up to ≅102 K/min) that inhibits the formation of the objectionable phases and limits elemental loss due to the short-time process. The samples containing ≅ 96% wt. of the MAX phase Ti3AlC2 are successfully synthesised using the proposed technique.
Key words: MAX phase, pressureless synthesis, fast heating, ball milling.
