摘要：

In this work we investigate influence of the composition and specific surface of a precursor on the porous structure of tantalum powders obtained via magnesium vapor reduction of the D cent D degrees D-2(5), MgD cent D degrees O-2(6) and Mg4D cent D degrees O-2(9). Sorption and nitrogen capillary condensation have allowed an increase in the specific powder surface to be established due to the increasing amount and specific surface of mesopores with a size below 10 nm.
