Abstract
A complex of methods is employed to study the properties of carbon condensate obtained by detonation of the enriched acetylene/oxygen mixture. The effect of the gas mixture composition and the methods to initiate detonation, which provide the preparation of ultrafine products, are analyzed. According to the powder X-ray diffraction and electron microscopy data, the detonation products are a carbon condensate consisting of coalescent amorphous particles with a size of ~100 nm.
