Abstract
An apparatus for the synthesis of diamond by the vapor-phase process using a combustion flame is provided with a cover set in place in the peripheral region of a combustion burner for enveloping the combustion flame and provided, when necessary, with gas inlets. A method for the synthesis of diamond by the vapor-phase process using the apparatus described above effects the diamond deposition by forming a combustion flame for synthesis of diamond and, at the same time, varying the relative parallel positions of the combustion flame and the substrate.
