METHOD FOR PRODUCING DIAMOND FINE PARTICLE HAVING EXCELLENT WATER DISPERSIBILITY, AND DIAMOND FINE PARTICLE-WATER DISPERSION

摘要

PROBLEM TO BE SOLVED: To provide a diamond fine particle water solution solving the problem that diamond fine particles of high concentration of 3 to 10 wt.% is inferior in water dispersibility, maintaining the physical and chemical properties of diamond, and excellent in water dispersibility at high concentration.;SOLUTION: Provided is a method for producing diamond fine particle powder excellent in water dispersibility at high concentration, obtained by subjecting diamond fine particle powder to heating treatment at 700 to 900°C for 30 min. or more in an inert gas atmosphere.;COPYRIGHT: (C)2015,JPO&INPIT
