1. Main characteristics, description of the offer.

Gas-Dispersed Synthesis (GDS) is a new highly productive method for obtaining of chemically pure (> 99,7% ) granulometrically narrow, spherically shaped, well disaggregated oxides of aluminum, zirconium, titanium, zinc, iron, etc. particles with an average size in a range 20 — 100 nm.

The method is based on combustion ( in specially organized two-phase flames ) of gas mixtures of appropriate metals particles (pure metals, mechanical mixtures or alloys of different metals). The target material is form as result of gase-phase condensation products of metals combustion in an oxidizing medium.

2. Innovations and advantages of the offer.

The proposed method has some significant advantages. It is very economical in terms of energy consumption, high performance (laboratory setting allows you to receive up to 1 kg per hour oxide powder (for comparison method gas phase condensation — a few tens of grams per day)), one-step, continuous and environmentally friendly.

3. Patent search and market substitutes’ comparative analysis.

The patent search in leading countries (USA, Great Britain, Japan, France, Germany, Canada) has shown, that the project corresponds to the level of world analogues. Analogues of the described method is aerosol and chemical reactors and series of other methods, based on combustion processes .

Methods based on burning of metal-organic and metal- inorganic liquids, as well as some other methods, which use combustion processes, lead to contamination of a nanoparticles surface by sulphides and chlorides. It is necessary to take into account and ecological problems connected with usage of sulfur, chlorine, bromine, iodine etc. Other known methods of metal oxides nanopowders obtaining have either low output (method  Gas Phase Condensation), or too power-consuming (method of vapor-phase synthesis — Physical Vapor Synthesis — PVP, plasma technologies etc.), or multistage (sol — gel technologies).

4. Domain of application. Potential customers of the final product / service.

The project can be realized for the industrial enterprises and organizations involved in the development and manufacture of new types of ceramics and composite materials, pigments, abrasive materials, catalysts. This method is demanding for the nanopowders metals oxides in ceramic industry and for nanotechnologies.

5. Profitability, market attractiveness, introduction and sales costs, price.

The GDS method mainly has no disadvantages of other methods. The method is economic in view of power inputs, continuous, single-stage, high-duty. The nanopowders purity directly connected to purity of initial raw material and, as rule, is higher.

6. Current stage of development. Existent results of introduction.

The method is protected by the patent of  USSR # 1832397 «Method of superdispersed metal oxides obtaining». Laboratory samples of metals oxides nanopowders are obtained. The elaboration was not applied in industry.
