Abstract
A method for vapor-phase synthesis of diamond comprises burning a raw material compound for synthesis of diamond thereby forming a combustion flame, disposing a substrate for deposition of diamond in said combustion flame, and keeping said substrate at a prescribed temperature, thereby inducing deposition of diamond on said substrate.
Claims8
A vapor-phase method for the synthesis of diamond, comprising the steps of burning a raw material compound in the presence of oxygen for deposition of diamond thereby forming a combustion flame containing at least an incomplete combustion region;
- disposing a substrate for deposition of diamond in said combustion flame, and maintaining said substrate at a temperature for deposition of diamond, thereby inducing deposition of diamond on said substrate.
