Carbon: Occurrence of Linear Forms in Natural Graphite.

Abstract

A study of several natural carbon formations, from geographical locations ranging from Celyon to California, revealed that the carbons contain small amounts of linear carbon forms, e.g., chaoite, alpha carbyne, and bete carbyne. The results indicate that these 'rare' carbon forms have worldwide distribution and, as with diamond, are prevented from transformation to graphite by a high kinetic barrier. (Author)
