Abstract
The sintering of combustion-synthesized titanium carbide was investigated relative to that of commercially available powders. Depending on the preparation parameters, the synthesized powders had variable shrinkages at the same sintering conditions. Moreover, the commercial powder experienced a higher densification than any of the powders prepared in this study. These observations are interpreted in terms of the influence of free carbon on the sintering process. Approximately calculated amounts of free carbon show an inverse relationship with the measured shrinkages. Experimental verification for this is provided by sintering data on carbon-doped commercial powders of titanium carbide.
The activation energies for sintering were determined as 390 ± 26 and 458 ± 13 kJ.mol-1 for the commercial and combustion-synthesized powders, respectively.
