Abstract

Recently, many results were reported by many institutes and companies all over the world for diamond particles or thin films synthesized on crystalline substrates, such as molybdenum, silicon etc. But diamond on amorphous or oxide substrates, were rarely reported. In this study, we used material of amorphous and oxide for substrates, for example quartz glass, Alumina.

We used unique apparatus of diamond synthesis. With our apparatus, completely closed system was used, no reaction gas was introduced to the chamber and no reactant gas was evacuated from it. We used graphite rod for heater and carbon source, at the same time.

And we compared results with this unique closed system and with conventional flow system. Carbon sources of gaseous state (methane) and solid state ( graphite ), and closed and flow system result the deference of synthesized diamond particles.
