Chemical vapor deposition method
Chemical vapor deposition method is a method for synthesizing diamonds at low temperature.
Spherical diamonds can be obtained by decomposing carbon-containing gases in a specific atmosphere and depositing them on a substrate.
This method can produce high-quality spherical diamonds, but the cost is high and the production efficiency is low.
Detonation method
The detonation method is a method for synthesizing diamonds under high temperature and high pressure conditions generated by the explosion of explosives.
Spherical diamonds can be obtained by controlling the type, amount and explosion conditions of explosives.
This method has low cost and high production efficiency, but the quality of the spherical diamonds obtained is relatively low.
