Abstract

We have done a series of experiments on diamond microcrystal formation in flowtubes. The system is designed to separate the discharge used to create atomic hydrogen from the organic molecules used as a carbon source. This creates a simplified chemical environment in which the species concentrations are kinetically rather than thermodynamically controlled. The flowtube enables us to examine kinetics of diamond formation under a variety of conditions and gives us some information about the rate of nucleation independently of the growth rate. 1.
