Abstract
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 Та2О5, MgТа2O6 and Mg4Та2O9. 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.
