Synthesis of High Purity Ti₃SiC₂ Powder by Vacuum Sintering

Abstract:

To investigate the possibility and reaction route of fabrication high purity Ti3SiC2 powders using coarse reactants by a relatively simpler method, Ti/Si/TiC mixtures (74μm in average size) added proper amount of aluminum were heated in vacuum sintering furnace with different sintering scheme. The effects of Al addition and temperature on the purity of resultant Ti3SiC2 powder were also examined. The results showed that over 99wt.% content Ti3SiC2 powders could be obtained at optimal temperature 1410°C-1420°C holding 90-120min with 0.10-0.20 Al addition (molar ratio). XRD, SEM and EDS results indicated that Ti5Si3 and TiCx were the main intermediate phases which redounded to synthesize Ti3SiC2 powder subsequently.
