Abstract
A process for synthesizing diamond includes bringing a reactant gas is brought into contact with a porous heating element to form an activated gas, and bringing the activated gas into contact with a substrate to deposit diamond thereon. An apparatus for synthesizing diamond includes a heating means member including a porous heating element, a substrate, and a diamond depositing member. The reactant gas is heated and activated uniformly to a high temperature appropriate for synthesizing diamond by bringing the reactant gas into contact with the porous heating element, whereby a high quality polycrystalline diamond film can be deposited over a wider area on the surface of the substrate.
