Abstract
A unitary composite structure having improved flexural strength and a reduced coefficient of thermal expansion comprising a heterogeneous combination of a carbonaceous reinforcing material interbonded with a matrix material, wherein the said matrix material is a poorly graphitizing carbonaceous pitch containing polymerized and cross-linked aromatic components is disclosed. Graphite electrodes comprised of the poorly graphitized pitch matrix material acting as a binder and/or an impregnant are also disclosed. Processes for the preparation of the poorly graphitizing pitch, the composite structure, and particularly the graphite electrodes are disclosed as well.
