Process For Recovery Of Niobium Values For Use In Preparing Niobium Alloy Products
US Patent:
4164417, Aug 14, 1979
Filed:
Apr 28, 1978
Appl. No.:
5/901069
Inventors:
Robert A. Gustison - Reading PA
Assignee:
Kawecki Berylco Industries, Inc. - Boyertown PA
International Classification:
C22B 3424, C22C 2702
US Classification:
75 84
Abstract:
The invention disclosed provides a process for recovering niobium values from aqueous hydrofluoric acid solutions by evaporating said solution to dryness and baking the residue at temperatures of 150. degree. to 250. degree. C. The solid residue is niobium oxyfluroide (NbO. sub. 2 F) which may then be exothermically reduced with aluminum in the presence of an alloying element such as iron, nickel, or chromium to produce a niobium alloy. The evaporated hydrofluoric acid may be recovered by condensing or absorbing the evolved vapors.
Dispersion-Hardened Lead Alloy
US Patent:
4003755, Jan 18, 1977
Filed:
Aug 22, 1975
Appl. No.:
5/606966
Inventors:
Robert Lawrence Gustison - Sinking Spring PA
International Classification:
H01M 228, C22C 1100
US Classification:
429178
Abstract:
A lead alloy is prepared by dispersing minor amounts by weight of silicon in a continuous lead phase. The alloy has a lesser density than unalloyed lead and has improved strength, excellent corrosion resistance, good electrical conductivity, and satisfactory workability.
