On the structure of glassy carbon

Materials Research Bulletin, 1976
Abstract Glassy carbons made by heating a phenolic resin to temperature ranging from 500 to 1000°C were studied by X-ray diffraction and small angle X-ray scattering. Crystallite size, interlayer spacing and submicroscopic void size show rapid variation for heat treatment temperatures near 700°C.

Raman spectra of glassy carbon

Journal of Applied Physics, 1974
The 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.

Reaction of glassy carbon with oxygen

Carbon, 1975
Abstract A glassy carbon, GC-30, from Tokai Electrode Manufacturing Co., Ltd. has been reacted in O 2 between 750 and 850°C. At low carbon burn-offs the reaction has an activation energy of 63 ± 3 kcal/mole. Changes in dimensions of samples as a function of burn-off at 900°C were studied.

Switching phenomena in glassy carbon

Carbon, 1973
Abstract Reversible switching effect was studied in carbonized polyfurfuryl-alcohol resin. Switching appears after heattreatment at a temperature of 300°C. The maximum temperature range for both heattreatment and measurements at elevated temperature was limited by melting of aluminum electrodes (659·7°C).

Measurements on glassy-carbon electrodes in saline

Medical & Biological Engineering & Computing, 1977
Results of measurements on glassy carbon used as physiological measuring electrodes and as stimulating electrodes are presented. The frequency dependence of the electrode impedance is shown to be comparable with that of metallic electrodes. Because of its inertness to body tissue, the glassy carbon electrode appears to have favourable properties for ...

Glassy carbon for maximum impact

Science, 2019
Materials 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 ...

Galvanomagnetic properties of glassy carbon

Carbon, 1963
Abstract 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.
