Synthesis of diamondlike nanoparticles under cavitation in toluene

Nanodiamonds that are obtained during cavitation synthesis in toluene [E. M. Galimov et al., Doklady Phys. 49 (3), 150 (2004)] are investigated. The procedure of chemical purification of nanodiamonds allowing for isolating a chemically pure product is developed, and diamond nanoparticles less than 10 nm in size are obtained. New data indicating that the fcc modification of carbon appears along with the diamond phase under cavitation synthesis and raising the question on the account of interaction types of carbon precursors are represented.
