METHOD FOR CONTROL OF MAGNETIC ADMIXTURES CONTENT IN NANODIAMONDS OF DETONATION SYNTHESIS Russian patent published in 2010 - IPC C01B31/06 B82B1/00 G01N25/02 G01N24/10

Abstract RU 2388688 C1

FIELD: nanotechnologies.

SUBSTANCE: nanodiamond is placed into installation for annealing, hydrogen is passed through and maintained at the temperature selected from the range of (900÷1100) °C, cooled down to room temperature. X-ray diffraction pattern is taken. Additionally spectrum of electronic paramagnetic resonance (EPR) is registered at room temperature. Availability of metal phases is identified.

EFFECT: invention makes it possible to increase sensitivity of magnetic admixtures content detection in nanodiamonds of detonation synthesis.
