โœฆ Synopsis

and A. Ragoss (Siemens-Planiawerke AG ftir Kohlefabrikate, Meitingenliiber Augsburg-Bundesrepublik Deutschland). The graphitization process of various cokes above all soft ones and of polycrystalline carbons made of them has been studied. Besides the changes of the usually determined physical properties as real density, electrical resistivity, thermal expansion and Young's modulus the evaluation of crystalline ordering parameters is described. The crystalline growth and the distortion is followed by studying the line profiles using the method of Warren and collaborators. These data shall accomplish the few ones published until now and shall open the possibility of correlating these crystalline ordering parameters to the well-known physical properties of polycrystalline carbon on different heat-treatments, and the behaviour of these graphites on neutron irradiation. First results obtained by high-temperature X-ray diffraction are described.

The viscosities and molecular size distributions of furfuryl alcohol resin binders are shown to have important influences on the fabrication and physical properties of graphites made from them. Increasing binder viscosity to about 2000 cp improves the physical properties of the graphite. Above this,
