Abstract
A method for producing a diamond material by contacting a fluorinated precursor with a hydrocarbon in a reactor and forming a combination in the absence of a metal catalyst; increasing the pressure of the reactor to a first pressure; heating the combination under pressure to form a material precursor; cooling the material precursor; and forming a diamond material.
