Research and Development on Advanced Graphite Materials. Supplement to Volume XI. Characterization of Binders Used in the Fabrication of Graphite Bodies

摘要

A typical coal tar pitch was separated into fractions which were analyzed and characterized by selected physical and chemical methods. The results indicated the presence of molecules consisting of from one to several aromatic clusters, each having a mean cluster size near four aromatic rings. Information was obtained on aromaticity, hydrogen distribution and substitution index. A study was made of the effect of temperature and different atmospheres on the plasticity of the various fractions of the pitch sample. (Author)
