Abstract
When a mixture of gases containing carbon is burned to form a film of diamond on a surface of a substrate held at an appropriate temperature, it is so burned as to form a substantially flat region of incomplete combustion lying in parallel to the substrate surface and contacting it, while the region is surrounded by an air-shielding gas stream or formed under a reduced pressure.
