摘要
process of obtaining powders of tantalum carbides using a tantalum powder as a precursor and toluene vapors as a carbon source is investigated. Powders of tantalum carbides TaC and Ta2C are obtained in the temperature range of 650-850 degrees C using magnesium as an in situ deoxidizer of tantalum. The specific surface of the powders is at a level of 8-25 m(2)/g. The average sizes of carbide crystallites are 7-16 nm. The powders are characterized by a mesoporous structure.
