Title:
NANOCRYSTALLINE DIAMOND, AND METHOD AND DEVICE FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2018/055661
Kind Code:
A1
Abstract:
[Problem] To make it possible to produce uniform sized nanocrystalline diamond particles without crushing diamond agglomerates. [Solution] A starting material gas that contains silicon and carbon is fed into a plasma space (P) formed inside a reaction chamber (2) to cause the silicon and carbon contained in the starting material gas to separate in a plasma environment, and the carbon is covalently bonded, by gas-phase synthesis, to the periphery of the silicon having an SP3 crystalline structure as a crystalline nucleus. The product thereof is then collected by a negatively charged collection receptacle (5) that is disposed directly below the plasma space (P).
