Purpose of the development: Suitable for the preparation of chemically pure (> 99.7%) of the granules symmetric narrow spherical well des agregovannyh nanopowder with a mean particle size in the range of 20 - 100nm oxides of aluminum, zirconium, titanium, zinc, iron and others.

Recommended application field: Development can be realized at the enterprises of the Ministry of Industrial Policy of Ukraine, enterprises and organizations engaged in the development and manufacture of new types of ceramics and composite materials, pigments, abrasives, catalysts.

Advantages over analogues: Patent Search in leading countries (US, UK, Japan, France, Germany, Canada) showed that the development meets the level of global peers. Analogues of the method include the aerosol chemical reactors and a number of other methods of obtaining nanooxides metals, which are based on combustion processes. The methods are based on the combustion of organometallic and meta inorganic liquids, as well as some other methods, which use combustion processes lead to pollution of the surface of particles of sulfide and chloride. Should pay attention to the environmental problems associated with the use in the production of compounds of sulfur, chlorine, bromine, iodine, and others. Other known methods of producing metal oxide nanopowder or have low productivity (Gas Phase Condensatіon method), or too power-hungry (by vapor phase synthesis - Physіcal Vapor Synthesіs - PVP, plasma technology, etc.), or a lot of stadial (ash-gel technology) .

The development stage readiness: tested in laboratory condition

Technical and economic effect: Method HDS no disadvantages of other methods. Method economic terms of energy consumption, continuous, single-stage, high-performance. Frequency nanopowder directly related to the purity of raw materials and usually has the highest. To illustrate the economic attractiveness of the design below shows a comparison of prices for metal powders nanooxides company Nanophase Technologіes Corporatіon (particle size 30-50 nm) and similar powders obtained by SDS from domestic raw materials (powders of metals zirconium, iron, titanium, zinc Volnogorsk Mining and Metallurgical Combine , Transcarpathian metallurgical Plant et al.). Prices of raw powder metals in Ukraine and Russia (AІ) close to the world.

Description of the development:
()
Synthesis gas-dispersion (SDS) - a new method for obtaining high-chemically pure (> 99.7%) of the granules symmetric narrow spherical well des agregovannyh nanopowder with a mean particle size in the range of 20 - 100nm oxides of aluminum, zirconium, titanium, zinc, iron, and al. The method is based incineration in specially organized a two-phase gas flame veil particles corresponding metals (pure metals, alloys or mechanical mixtures of different metals). The desired product is formed by the condensation of gaseous products of burning metals in an oxidizing environment.
