Large-Scale Fabrication of Ti3AlC2 Powder with High-Purity
A synthesis method of high-pure Ti3AlC2 powder with a large scale was presented as pressureless synthesis using TiC, Ti and Al powders as starting materials at 1300~1450°C in flow Ar. The different raw material scales were tested from 2 g to 1.0 kg, and the results showed that the purities of Ti3AlC2 powders could be kept around 97 wt% at different scales of raw materials. SEM observation and particle size analysis revealed that the synthesized Ti3AlC2 powders were uniform and around 5 μm in particle size. This method can be used for mass production of Ti3AlC2 powders with high-purity.
