| 摘要 |
A manufacturing method of diamond powder of the present invention comprises a step of forming a seed particle including diamond on a substrate; a step of injecting source gas in a reaction chamber having the substrate and a filament positioned therein; a step of heating the substrate; a step of activating the source gas by heating the filament; a step of separating the seed particle from the substrate by using the heated filament; and a step of growing diamond on the seed particle separated from the substrate by using the activated source gas. According to the manufacturing method of the present invention, diamond powder can be manufactured in a gas-to-particle synthesis method. |
