  • Patent number: 4490244
    Abstract: Graphite having a coefficient of thermal expansion of less than 5.times.10.sup.-7 cm/cm/.degree.C. over the range of 0.degree.-50.degree. C. is produced from premium petroleum cokes. The cokes are produced from feedstocks selected and blended on the basis of high resolution nuclear magnetic resonance spectroscopy of the hydrogen atoms in the raw material and multiple linear regression analysis of the various NMR bands as applied to a statistically significant number of feedstocks known to produce premium needle cokes together with a variable relating to thermal reactivity used to derive a predictive equation for the coefficient of thermal expansion.
