During the period from April 1 through May 31, 1958, experimental work centered about the preparation of specimens for graphitization. Sufficient standards were prepared to obtain preliminary information on the graphitic properties of: the pitch-bonded calcined petroleum coke standard, a pitch-bonded coke-thermax mixture, the standard mix containing added metal carbide, and a mix bonded with furfuryl alcohol. In the preparation af these, it was found that the packing characteristics of the No. 80 calcined petroleum coke are more strongly influenced by the proportion of added furnace carbon than was previously supposed. This influence is explicable from packing theory. It was experimentally determined, and confirmed by communications from other researchers, that the furfuryl alcohol polymer is highly sensitive to oxidation during carbonh-zation, so that a swept inert gas atmosphere must be substituted for ordinary packed sagger systems when this binder is used. It is recommended that this program be renewed, to permit standardization of the mixing, forming, and baking techniques of furfuryl alcoholbonded mixes as completely as has been done for pitch-bonded ones; and to develop graphite bodies of high structural strength on a sound basis of structural considerations.
