Filed:

Nov 4, 1976

Appl. No.:

5/738671

Inventors:

Leslie Harrisville Juel - Lewiston NY
Kenneth Wayne Tucker - Elizabethton TN

Assignee:

Great Lakes Carbon Corporation - New York NY

International Classification:

B32B 302

US Classification:

428 65

Abstract:

A pad of conductive material composed of particulate carbon and an organic binder is provided which acts as a spacer between coaxially placed carbon electrode columns when they are subjected to resistance heating by passing electric current lengthwise through the columns from electrodes held against the ends thereof.

Filed:

Apr 11, 1988

Appl. No.:

7/183303

Inventors:

Louis A. Joo - Johnson City TN
Kenneth W. Tucker - Elizabethton TN
Jay R. Shaner - Johnson City TN

Assignee:

Great Lakes Carbon Corporation - New York NY

International Classification:

H01M 496
C25B 1112

US Classification:

429 40

Abstract:

A porous graphite electrode for a fuel cell is formed by impregnation of a cellulosic filter paper by coating or impregnating with a low coke yield impregnant on the active center area and with a high coke yield impregnant on the edges, followed by curing, baking, and graphitizing the electrode to form a monolithic porous graphite electrode base with a dense low porosity area at the edges with a less dense higher porosity center working area.

US Patent:

Filed:

Aug 27, 1979

Appl. No.:

6/069846

Inventors:

Kenneth W. Tucker - Elizabethton TN

Assignee:

Great Lakes Carbon Corporation - New York NY

International Classification:

H01B 106

US Classification:

252507

Abstract:

Chloro-hydrocarbons are used as pitch binder modifiers to improve the strength, density and electrical properties of carbon and graphite articles produced from carbonaceous particles, binders, and additives, and are particularly useful in manufacture of electrodes used in ultra high powered electric arc steel furnaces.

US Patent:

Filed:

Jul 27, 1981

Appl. No.:

6/287124

Inventors:

Kenneth W. Tucker - Elizabethton TN
Frank E. McCown - Bristol TN

Assignee:

Great Lakes Carbon Corporation - New York NY

International Classification:

C25B 1104
C25C 312

US Classification:

264 295

Abstract:

Titanium diboride graphite composite articles are produced by mixing TiO. sub. 2, petroleum coke and a binder to form a plastic dispersion. Articles are shaped by molding or extrusion and baked to carbonize the binder to form a baked carbon-TiO. sub. 2 composite. The article is impregnated with a molten or dispersed boron compound, then heated to drive TiB. sub. 2 forming reaction. The article is then further heated to a graphitizing temperature to form a graphite-TiB. sub. 2 composite useful as a cathode component in a Hall aluminum reduction cell.

International Classification:

C25C 306
C25C 702
C01B 3504

US Classification:

204294

Abstract:

TiB. sub. 2 -carbon composites are produced by mixing the raw materials comprised of carbon, TiB. sub. 2, pitch, and other reactants, forming a shaped article, processing in a nitrogen atmosphere up to 2100. degree. C. , and in a noble gas above 2100. degree. C.
