Abstract: One of the major challenges in the development of nanostructured/ultrafine non-oxide ceramics is the synthesis of non-agglomerated nanosized ceramic powders. Here, we investigate carbothermal reduction to obtain spherical titanium carbide (TiC) nanoparticles smaller than 100 nm in diameter. Using a combination of characterization techniques, it has been confirmed that optimum thermal reduction conditions include a temperature of 1350oC with 1 hour holding in an argon atmosphere. A three-parameter Weibull distribution function provides a satisfactory fit for the size distribution of the synthesized TiC nanoparticles. Varying the synthesis time at 1350oC revealed the particle coarsening exponent ā€˜nā€™ to be 2.9 and that particle shapes change from spherical at 1 hour to more faceted at longer holding times of 4 hours.
