Abstract

One of the industrially scalable methods for the synthesis of diamond crystals is shock compression of graphite. The method includes shock compression of graphite with explosives (RDX). Typical sizes of polycrystalline diamond particles produced by the method are in the range from 50 nm to 2 μm. We submit a method for deagglomeration of that diamond particles and production of stable hydrosol of monodisperse particles with positive electrokinetic potential. The mean size of isolated diamond particles in the hydrosol is 4 nm. The method includes chemical purification of the commercial diamond powder, annealing of purified powder in hydrogen, and followed centrifugation.
