Process For Producing Niobium And Tantalum Compounds

US Patent:
6984370, Jan 10, 2006
Filed:
Jan 14, 2002
Appl. No.:
10/047440
Inventors:
Patrick M. Brown - Exton PA, US
Raymond C. Pedicone - Pottstown PA, US
Michael G. Madara - Shillington PA, US
Assignee:
Cabot Corporation - Boston MA
International Classification:
C01G 35/00
US Classification:
42359417
Abstract:
A process for producing valve metal oxides, such as tantalum pentoxide or niobium pentoxide with a narrow particle size distribution within a desired particle size range, is provided. According to the process of the present invention, the valve metal fraction from digestion of valve metal material containing ore is processed under controlled temperature, pH, and residence time conditions to produce the valve metal pentoxide and pentoxide hydrates. Also, disclosed are new tantalum pentoxide and niobium pentoxide products and new tantalum pentoxide precursors and niobium pentoxide precursors.
