MANUFACTURE OF GLASSY CARBON

Glass or vitrified carbon is produced by thermal degradation of polyphenylene sulfide or a substituted compound thereof by additions of an oxide of a sulfide-forming metal, such as Fe2O3, which is added in a weight amount of at least about 1% and preferably about 10%, in order to accelerate the degr...

Beschreibung
Zusammenfassung:	Glass or vitrified carbon is produced by thermal degradation of polyphenylene sulfide or a substituted compound thereof by additions of an oxide of a sulfide-forming metal, such as Fe2O3, which is added in a weight amount of at least about 1% and preferably about 10%, in order to accelerate the degradation process, and resultant admixture is heated to a temperature above about 150 DEG C. and thereafter the temperature is increased during the course of the reaction. The inventive process is useful for production of chemically resistant glass carbon fibers, glass carbon electrodes, glass carbon containers, etc.
