GRAPHITE TECHNOLOGY. Period covered April 1, 1957-September 1958
The two-fold purpose of this investigation has been to correlate the properties of smalls multicrystalline graphite specimens with the factors believed to influence them, and to assess the probability that graphite can conform to engineering specifications. The technique of differential thermal analysis was found applicable to investigating binder pyrolysis. Three promising binder materials were selected for future work: coal-tar pitchs furfuryl alcohol, and phenolberzaldebyde. The most illuminating properties cf experimental mixtures were found to bei apparent (water immersion) densitys dynamic (sonic) meduluss volume electrical resistance, and flexural strength. Measurements of medulus, strength, and thermal expansion have been carried out tomore »
