Abstract
Disclosed in this specification is a process and apparatus for producing a diamond substance. A first mixture comprised of oxygen and a hydrocarbon gas is formed in the first inner nozzle. The first mixture is ignited to produce a flame core. A second mixture comprised of hydrogen and oxygen is formed in an outer nozzle; the second mixture is ignited to produce a flame sheath. The flame sheath is disposed around the flame core so that the flame sheath surrounds the flame core and shields the flame core from the ambient atmosphere; thereby producing a composite flame; and the composite flame is contacted with a substrate.

A process of producing a diamond substance, comprising the steps of:
- a. forming a first mixture comprised of oxygen gas and a hydrocarbon gas, wherein said hydrocarbon gas contains from about one percent to about ten percent molar excess of carbon for each mole of oxygen present in such first mixture;
- b. igniting said first mixture to produce a flame core;
- c. forming a second mixture comprised of hydrogen and oxygen, wherein:
- 1. said second mixture is comprised of a molar excess of said hydrogen over the moles of said oxygen present in the second mixture,
- 2. said second mixture contains up to about 10 volume percent of hydrocarbon gas;
- d. igniting said second mixture to produce a flame sheath;
- e. disposing said flame sheath around said flame core so that said flame sheath surrounds said flame core and shields said flame core from the atmosphere, thereby producing a composite flame;
- and
- f. contacting said composite flame with a substrate.
