Tantalum Metal Power With Controlled Size Distribution And Products Made Therefrom

View page

US Patent:

59868775, Nov 16, 1999

Filed:

Jul 28, 1998

Appl. No.:

9/123818

Inventors:

Viren M. Pathare - Allentown PA
James Allen Fife - Reading PA
Hongju Chang - Wayne PA
Roger W. Steele - Neffs PA
Lee M. Ruch - Shillington PA

Assignee:

Cabot Corporation - Boston MA

International Classification:

H01G 904

US Classification:

361508

Abstract:

A capacitor having a central electrode body having sintered metal anode with an electrode lead, the anode having a sintered product produced from a tantalum powder having deagglomerated particles such that the product of the volume mean diameter in microns multiplied by the specific surface area measured in m. sup. 2 /g is a number in the range of below about 25. Capacitors having a central electrode with the anode produced from a sintered product produced from a heat treated and oxidized tantalum powder wherein the oxidized particle size is greater than about 0. 7 m. sup. 2 /g. Capacitors are defined in terms of anodes produced from powders having specified ratios of Scott Bulk Density to surface area or ratio of die fill rate to surface area.

US Patent:

59548568, Sep 21, 1999

Filed:

Apr 25, 1996

Appl. No.:

8/638922

Inventors:

Viren M. Pathare - Allentown PA
James Allen Fife - Reading PA
Hongju Chang - Wayne PA
Roger W. Steele - Neffs PA
Lee M. Ruch - Shillington PA

Assignee:

Cabot Corporation - Billerica MA

International Classification:

B22F 100

US Classification:

75255

Abstract:

A process for sizing (i. e. , comminuting) a tantalum powder including agglomerates of smaller particles, which process yields a tantalum powder having an as-comminuted agglomerate size distribution with the product of the Volume Mean Diameter, MV (in microns as measured by light scattering techniques such as Microtrac analysis), times specific surface area, BET (m. sup. 2 /g), being less than about 25. These powders after sizing typically have ratios of Scott Bulk Density : BET Surface Area in the range from about 20 to about 35. Also provided are powders having a substantially unimodal and narrow agglomerate size distribution in all stages of production, namely after sizing (i. e. , deagglomeration by comminution), thermal agglomeration (i. e. , heat treatment), and deoxidation.
