Abstract

Abstract

This paper reports the effect of pretreatment of graphite on the diamond growth. Big size diamonds of good quality were synthesized, in which the inclusions of Ni, Mn, Co, Si were reduced and N content increased. It was found that the diamond grew on both side of catalytic disks. The pretreatment method not only improved the quality of diamond, but also might provide basis for understanding of the mechanism of graphite transformation to diamond.
