Abstract

The recently characterized " white " allotropic form of carbon has been produced at high temperature and low pressure during graphite sublimation. Under free-vaporization conditions above ∼2550°K, the white carbon forms as small transparent crystals on the edges of the basal planes of graphite. The interplanar spacings of this material are identical to those of a carbon form noted in graphitic gneiss from the Ries Crater.
