<p>An ingot-derived unagglomerated (or pre-agglomerated) tantalum powder composition includes a platelet tantalum powder having an average FSSS of less than two micrometers, preferably in the range of 0.6 to 1.1 micrometers, a Scott density not greater than about 30 g/in<3>, and a BET surface area of at least 0.7 m<2>/g. In one embodiment of the invention, such powder is agglomerated and milled to form a tantalum powder product having a particle size of about 2 to 3 micrometers, a BET surface area of about 0.43 m<2>/g, a Scott density in the range of 18 to 27 g/in<3>.</p> |
