Raman spectra of glassy carbon
Journal of Applied Physics, 1974The Raman spectrum of glassy carbon has been measured. Two broad lines are observed at 1340 and 1590 cm−1. These results are consistent with the turbostratic structure, which has been suggested for glassy carbon, with a particle size La of approximately 30 Å.

Journal of Materials Science, 1970
It is shown that phenol-hexamine polymers may be extruded from the melt to produce fibres which may be carbonised to form fine high-strength glassy carbon fibres with a tensile strength of up to 2 GNm−2 (300 000 Ib in−2) after 900° C heat-treatment. The fibres have a specific modulus of ∼5 Mm compared with ∼14 Mm for carbonised polyacrylonitrile fibres

The Structure of Glassy Carbon
Japanese Journal of Applied Physics, 1986The structure of a glassy carbon made by Tokai Electrode Company has been studied by analyzing X-ray diffraction patterns from six types of sample subjected to different heat-treatments at temperatures from 700°C to 3,000°C. The diffraction intensity of AgKα1 radiation was measured to s = 22.1 Å-1 by the method of fluorescence excitation, and the ...

Glassy carbon for maximum impact
Science, 2019Materials Science Materials designed for impact absorption need to be able not only to cope with high-stress deformations but also to accommodate high strain, as the energy absorbed is the integral of the stress-strain response. Although lightweight designed materials, such as those based on trusses, can show high strength or high deformability, they ...

Submicroscopic voids in glassy carbon
Journal of Materials Science, 1973Small angle X-ray scattering by glassy carbon was used to establish the characteristic of submicroscopic porosity. A monochromatized linear beam was used and corrections were made to obtain the scattering curve free of aberration. From analysis of the scattering curve, the voids were deduced to be oblate ellipsoids of revolution.

Galvanomagnetic properties of glassy carbon
Carbon, 1963Abstract The Hall coefficient, magnetoresistance and electrical resistivity of an extremely hard carbon, namely glassy carbon developed by the Tokai Electrode Mfg. Company, were investigated as function of heat-treatment temperature from 1000 to 3200°C at three ambient temperatures 20, 77 and 300°K.
