METHOD FOR PRODUCING SUPERDISPERSED MATERIALS Russian patent published in 2003 - IPC

FIELD: production of superdispersed materials. SUBSTANCE: method for producing superdispersed materials using high pressures and high temperatures developed during detonation of explosives depends on impact wave loading of source powdered material layer with contact charge of explosive followed by dispersion in explosion chamber. Prior to first blowing-up explosion chamber is evacuated. Next explosions are made in the environment of detonation products at atmospheric pressure. Prior to evacuation non-polar liquid or solution of surface-active substance in distilled water is poured onto explosion chamber bottom. Used as source material powder is mixture of homogeneously mixed up powders having boiling temperature up to 3000 K or chemical compound powder having decomposition temperature up to 3000 K. EFFECT: enlarged range of synthesized superdispersed materials; enhanced output. 4 cl, 1 dwg
