A study of the carburization of tantalum was carried out by reacting it with CO at temperatures in the range from 1073 K to 1573 K. In addition to Ta2C, Ta2O5 also formed as an intermediate product before full conversion to TaC. A thermodynamic analysis showed that such a complex reaction path was followed because the carburizing reactions generate enough CO2 to oxidize the metal. The reaction of tantalum with COCO2 gas mixtures was also investigated. The kinetics of reaction is discussed in terms of the reaction mechanisms and the reacting gas composition.
