Title:
CHLORINE TERMINATED DIAMOND FINE POWDER, AND METHOD FOR PRODUCING THE SAME
Document Type and Number:
Japanese Patent JP2007001790
Kind Code:
A
Abstract:
To provide diamond fine powder utilizable as the stock for a functional material such as the additive and the carrier of pharmaceuticals.
Single crystalline diamond particles are pulverized, and classified so as to be starting diamond fine powder with the D50 average particle size of ≤1 μm. The starting diamond fine powder is charged into a sealed vessel, and is held at 150 to 500°C. Gaseous chlorine is made to flow therein, and is brought into contact with the diamond particles, and chlorine is chemically adsorbed on the surfaces of the particles so as to be diamond fine powder chlorine terminated diamond fine powder in which ≥0.2 mass% chlorine is adsorbed on diamond.
