Efficient Synthesis and Characterization of Nanostructured TiC Powder by Reaction Milling

Nanocrystalline TiC powder is synthesized from corresponding elemental constituents by reaction milling in a dual drive planetary mill. The study shows nanocrystalline TiC powder could be produced from Ti + graphite and Ti + activated carbon powder after 10 h of milling. Raman spectroscopy provides evidence in support of formation of TiC after 10 h of milling. Scanning electron microscopy reveals the size reduction and morphology of particles at different stages of milling. Transmission electron microscopy shows the formation of nanocrystalline TiC powder with particle size in the range of 50–200 nm. The lattice parameter of TiC (fcc) has been precisely calculated from first two strong peaks as 0.42 nm.
