Effect of Ta2O5 Precursor Morphology on Characteristics of Magnesiothermic Tantalum Powders

Inorganic Materials Aims and scope

Abstract—

We examine the effect of the morphology of tantalum pentoxide on the properties of tantalum powders prepared by reducing the oxide with magnesium vapor. The morphology of tantalum pentoxide used as a precursor is shown to influence the particle size composition and morphology of the synthesized tantalum powders and the capacitor anodes produced from them. Magnesiothermic tantalum powders are obtained that ensure a specific charge of capacitors at a level from 120 000 to 150 000 μC/g.
