Abstract
Combination of the sol-gel technique, which allowed us to obtain fine-dispersed, homogenious, active starting system Ta2O5 - C, and carbothermal synthesis under vacuum resulted in nano-sized tantalum monocarbide synthesis at a relatively lowtemperature of 1200±50°C. The obtained product was investigated by means of XRD-analysis and transmission electron microscopy. The average size of TaC particles is 20-40 nm, the size of crystallites (calculated by the Sherrer method) is 4-8 nm.
