METHOD FOR OBTAINING NANODISPERSIVE CARBONEUM (VERSIONS) AND DEVICE FOR THIS EFFECT Russian patent published in 2009 - IPC C01B31/00 B82B3/00 

FIELD: nanotechnologies.

SUBSTANCE: invention relates to nanotechnologies and can be used at production of solidphase nanostructurised materials, in particular, ultradisperse diamonds, fullerenes and carbon nanotubes. The mixture with the negative oxygen balance, consisting of carbon-bearing substances and oxidiser is prepared. Acetylene or kerosene are used as carbon-bearing substances. The mixture containing acetylene is injected into the detonation chamber made in the form of semi-closed resonant chamber 2, in the following manner: that with the excess oxidiser factor of less than 0.14 is injected through porous face wall 5, and that with the excess oxidiser factor of more than 0.96 - through the annular supersonic nozzle 4. The mixture containing kerosene is injected into chamber 2 in the following way: that with the excess oxidiser factor of less than 0.12 is warmed up at pressure of 0.2-25 MPA up to 640-860°C and is injected through porous face wall 5, and that with the excess oxidiser factor of more than 0.9 is warmed up at the pressure of 0.6 MPA up to 640-860°C and is injected through annular supersonic nozzle 4. In chamber 2, by means of initiator 3, the mixture detonation is made. The process is carried out periodically in quasi-stationary regimen at frequency of 100-20,000 Hz at the rate of detonation products cooling of 2·10⁵-10⁶ K/s. Labouriousness of the process is decreased, the mass and dimensions of the device are reduced and quality is improved due to depression of impurities in detonation products at their fast emission into vacuum or inert medium.

EFFECT: decreased labouriousness of the process, smaller mass and dimensions of the device, improved quality.
