Title:
RESEARCH AND DEVELOPMENT ON ADVANCED GRAPHITE MATERIALS. VOL. XXXII. STUDIES OF BINDER SYSTEMS FOR GRAPHITE

Abstract:
Binder systems were investigated with respect to their thermosetting characteristics both to replace pitch-sulfur combinations presently used in the pressure-curing process and to provide binders for development of new graphite grades. The binder systems included a prepolymerized furfuralalcohol resin b pitch, furfural, furfuryl-alcohol combinations c pitch with a ferric chloride catalyst and d pitch with oxidizers such as inorganic persulfates, chlorates and oxides. Acenaphthylene pitch, a new binder, was investigated with regard to thermosetting properties when used in the pressurecuring process. These binder systems were used in the fabrication of graphite articles and property determinations were made on the finished graphites. The binder modifications or systems investigated have produced no outstanding advantages over the pitch-sulfur system for use in the pressurecuring process. The most promising of the new systems was pitch combined with oxidizing agents other than sulfur, which produced a thermosetting binder of high coking value and which was comparable to the pitch-sulfur binder in other properties.
