Journal ArticleDOI
Diamond synthesis from gas phase in microwave plasma
TL;DR: In this paper, a crystal diamond predominantly composed of {100} and {111} faces was grown on a non-diamond substrate from a gaseous mixture of hydrogen and methane under microwave glow discharge conditions.
Journal ArticleDOI
Vapor Deposition of Diamond Particles from Methane
TL;DR: In this article, the structure of microcrystalline diamond deposits was identified by electron diffraction and Raman scattering, and cubo-octahedral or multiply-twinned crystals were obtained.
Journal ArticleDOI
Growth of diamond particles from methane-hydrogen gas
TL;DR: In this article, a mixture of hydrocarbon and hydrogen gases was passed through a heated reaction chamber in which a hot tungsten filament was held near the substrates, and the deposit was identified by reflection electron diffraction and Raman spectroscopy.

Method for synthesizing diamond
TL;DR: In this paper, a method for synthesizing diamond was proposed, where hydrogen gas which has passed through a micro-wave non-electrode discharge and mixed with hydrocarbon gas, or a mixture gas consisting of hydrocarbon and hydrogen after its passing through a non-electric discharge, is introduced onto the surface of a substrate heated to a temperature of from 300° to 1300° C. to decompose hydrocarbon in its energetically activated state for the diamond deposition.
Journal ArticleDOI
Sintering behaviour of the diamond-cobalt system at high temperature and pressure
TL;DR: In this paper, a powder mixture of diamond and cobalt was consolidated in situ on a WC-10 wt % Co base at temperatures of 1300 to 1500° C under a pressure of 5.8 GPa.
