US Patent:

46263330, Dec 2, 1986
Filed:

Jan 28, 1986
Appl. No.:

6/823438
Inventors:

Duane R. Secrist - Elizabethton TN
James M. Clark - Johnson City TN
Henry E. Grindstaff - Memphis TN
Assignee:

Great Lakes Carbon Corporation - Briarcliff Manor NY
International Classification:

C25C 312
US Classification:

204286
Abstract:

An anode assembly for an electrolytic cell for molten electrolysis has a cermet connector with a lower electrical resistivity than the anode threaded into the cermet or ceramic anode in the green or calcined state and then sintered to form an anode assembly having a low joint resistance at the cell operating temperature.

Filed:

Mar 16, 1983
Appl. No.:

6/475951
Inventors:

Duane R. Secrist - Elizabethton TN
James M. Clark - Johnson City TN
Henry E. Grindstaff - Elizabethton TN
Assignee:

Great Lakes Carbon Corporation - New York NY
International Classification:

C25C 306
C25C 312
C25C 316
US Classification:

204243R
Abstract:

An improved anode assembly for an aluminum electrolysis cell is formed by the process of shaping an anode 10 and a cermet connector 12 from powders, machining said articles, and sintering said articles. The cermet connector mates with the anode via a threaded joint located at its region of high temperature 14 during operation thereof to avoid excessive ohmic losses. Mechanical support can be provided by the threaded joint or through the use of separate mechanical suspension bars 22.
