Preliminary data are presented illustrating the properties of molded multicrystalline graphite made using calcined petroleum coke (in some instances mixed with a thermal carbon) bonded with coal tar pitch, furfuryl alcohol, or limited mixtures of the two. No conclusions have yet been drawn regarding the relation between these properties, since a large number of specimens remain to be measured. Most obvious is the difficulty of achieving a sound structure from bodies of maximum green density, particularly when the binder is not thermoplastic. Graphitized specimens made with furfuryl alcohol reflect the high density of the binder coke. Xray data show that this coke is poorly graphitizable as compared to pitch; modulus and electrical resistance data show it to be more dense. A full description of the use of differential thermal analysis and dilatometry in investigating the behavior of thermosetting resins is appended. For preceding period see ARF-6039-3. (auth)
