In the United States Patent and Trademark Office Application for Letters Patent.

Abstract

Large diamond crystals (i.e. greater than 100 microns) are grown at low pressure by placing a clean substrate in a high atomic hydrogen flux atmosphere that allows a growing diamond surface to remain hydrogen terminated. This atmosphere can be provided by heating the substrate in the feather portion of a flame created by the combustion of a mixture of oxygen and acetylene. The size of the crystals and the rate of formation of those crystals are comparable to those obtained by HPHT processes. Patent applications. (JS)
