A REVIEW OF GLASSLIKE CARBONS

Abstract

A relatively new group of carbons having several characteristics resembling glass is of sufficient interest in connection with technological demands for improved materials to prompt this report. The generic term 'glasslike' is appropriate for these carbons because they exhibit a glassy surface appearance, conchoidal fracture, internal-friction characteristics resembling glass more closely than normal graphite, and gas impermeability comparable to glass. The structure of glasslike carbons is not well understood; it resists change by graphitization at temperatures up to about 3000C. The report reviews the preparation, formation mechanisms, structure, properties, and applications of glasslike carbons. The unique combination of properties and resulting potential applications has stimulated manufacture of glasslike carbons by several companies. Available property data on the various products are included.
