PCT No. PCT/JP90/01545 Sec. 371 Date Jul. 25, 1991 Sec. 102(e) Date Jul. 25, 1991 PCT Filed Nov. 28, 1990 PCT Pub. No. WO91/08329 PCT Pub. Date Jun. 13, 1991.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.
