Abstract
PURPOSE:To synthesize uniform diamond granules in large quantities at a high speed by decomposing an org. compd. having methyl groups with equilibrium plasma in a diluting gas reactive with carbon and/or an inert gas to synthesize diamond on a heated substrate or reaction catalyst. CONSTITUTION:A substrate or reaction catalyst 1 is set at a heatable part in a reaction furnace 4 and heated to 300-1,500 deg.C. The furnace 4 is evacuated to <=10<-2>Torr and an org. compd. having methyl groups such as acetone and a diluting gas reactive with carbon and/or an inert gas are introduced into the furnace 4 from a gas feeding system 3. At the same time, DC are discharge is caused in a torch 2 to generate equilibrium plasma. The org. compd. is decomposed with the plasma in the vapor phase or brought into a reaction to synthesize diamond on the substrate or reaction catalyst 1 in the vapor phase.
