Formation of TaC Nanorods with a Low-Temperature Chemical Route

Tantalum carbide (TaC) nanocrystals have been successfully synthesized at 650 °C through a solid-state reaction in an autoclave. Transmission electron microscopy images show that the TaC crystallites consist of nanorods with a typical size of about 40 × 800 nm. Some uniform particles with an average size of about 40 nm also exist in the sample.
