The colloid theory of diamond nucleation and growth at high pressures
Abstract
The characteristics of diamond nucleation and growth at high pressures are examined from the standpoint of the colloid theory of diamond nucleation proposed by Fedoseev and Deryagin (1979). The theory is based on the well-known fact that during the dissolution of polycrystalline graphite materials, not only graphite atoms but also graphite crystals pass into carbon solution in molten metal. These graphite crystals are then transformed to diamond nuclei through a fluctuation or a martensitic transition in the solid phase.
