Abstract
Diamond is produced by chemical vapor deposition on a substrate by hot filament activation of a hydrogen-hydrocarbon gas mixture. An edge of the substrate faces the filament at a distance therefrom up to about 1 mm and preferably about 0.3-0.7 mm., and the substrate is moved relative to the filament to maintain this spacing as diamond forms thereon. Diamond formation proceeds at an improved rate, and in single crystal configuration under certain conditions.
