Tensile Properties of Glassy Carbon to 2,900° C

Abstract

GLASSY carbon is a turbostratic form of carbon which is produced by carbonizing a polymer under carefully controlled conditions of temperature and pressure. It has a density of 1.5 g/cm3 and is reported to have a very low gas permeability1. Tensile properties of two grades of glassy carbon, which the manufacturer (Tokai Electrode Manufacturing Co.) calls ‘GC 20’ and ‘GC 30’, have been measured from room temperature to 2,900° C. These grades are reported to have been heat-treated at 2,000° and 3,000° C, respectively.
