Title: Production of diamond with combustion flame method
Inventor: YOSHIDA TSUNORU
IPC: C30B29/04
Filed: 1991-12-30
Abstract: PURPOSE:To improve the conversion rate of gaseous raw materials to diamond by forming the sectional shape of a gas ejection port to a special deformed shape and alternately repetitively blowing the reducing flames and oxidizing flames of combustion flames to one point assumed on a substrate. CONSTITUTION:A gas ejection nozzle 11 formed with the slit gas ejection port 15 of the deformed shape having the ratio (x/y) of the major axis (x) and minor axis (y) of the sectional shape ranging from 1.09 to 27 at the front end 13 is used. The formed combustion flames indicate peaks of the two reducing flames along the major axis (x) direction when the gases for combustion (gaseous raw materials) are ejected from the ejection port 15 and are burned. The reducing flames hit on the substrate 21 at the two points corresponding to the reducing flame peaks and the oxidizing flames hit on the substrate 21 in the regions around these points. The respective points of the substrate 21 are alternately exposed to the oxidizing flames and the reducing flames and the diamond is gradually precipitated and deposited when the center of the substrate 21 and the center of the ejection port 15 are deviated in this state, and the blowing of the combustion flames to the substrate 21 is continued while the substrate 21 is kept rotated.
