Method and high pressure reaction vessel for quality control of diamond growth on diamond seed

摘要: Improvements are provided in reaction vessel construction used the growth of diamond by process disclosed U.S. Pat. No. 3,297,407 -- Wentorf, Jr. In assembly this invention, plug catalyst-solvent material is disposed between source carbon and seed as patent and, addition, separated from means for isolating until after latter has become saturated with carbon. preferably under surface metal covered suppressing nucleation. The nucleation usually form a disc may completely cover underside or have hole therethrough juxtaposition to seed/isolating combination(s). When both employed, capability simultaneously preventing dissolution spurious
