Technology

Nanopowder production is associated with a number of technological challenges. The most common of existing production methods involve chemicals. In particular, the obtaining of silicon dioxide based on the combustion of silicon tetrachloride, which is dangerous and environmentally harmful chemical process. The same fact is caused by limitations of common methods in relation to the choice for the production of substances available.

Under each substance (or group of substances) a specific technology is being developed that significantly increases the cost of the production process. In this case, the obtained powders have a wide spread (variance) of particle sizes, which in some cases, significantly affect the properties of the final product. In most methods the manufacturer cannot control the size of the obtained nanoparticles and therefore has to modify the technology to introduce additional catalysts, etc.

At the heart of our process is a patented method of obtaining powders by the evaporation of the raw material on electron accelerator followed by the cooling the high-temperature vapor and condensation of substance into very small particles (nanoparticles) which then become highly dispersed (nano-size) powders. This technology can be used to produce a wide range of nanoscale powders of oxides, metals, semiconductors, nitrides and carbides.

The uniqueness of this technology is in the fact that:

  • It is universal for a wide range of simple materials. The technology suits all materials and does not require any adaptation. Nanopowder is produced in one stage and does not require additional preparation or post-production;

  • Technology allows you to control all key parameters of finished products due to changes in the regime of installation and adjust to the demands of any customer;

  • Our technology is environmentally friendly which is one of the most significant advantages over the chemical methods as does not produce any harmful emissions;

  • It has one of the highest performances and is a low cost process used in the production of nanopowders, such as metals.

Advantages of the technology result in the advantages of the final products:

  • Particles size which ranges from 15 to 200nm can be controlled by the settings;

  • Small range of particle sizes within one type of nanopowder;

  • Since the technology does not involve chemicals, the purity of the product is determined only by the purity of raw materials;

  • The possibility to modify the surface of the particles;

  • The combination of these factors allows the simultaneous control of the four parameters to produce nanopowders that ideally suit to the needs of each customer.



Applications

Nanosized powders are widely used:

  • as fillers for composite materials;

  • in electronics (optoelectronics, fiber optics, conductive coatings and fabrics, ferromagnetic liquid);

  • in pharmacy and cosmetics (sprays, lotions, powders, ointments, creams, pastes);

  • as dispersants in the production of caked products;

  • thixotropy of fluids in the production of lacquers and paints;

  • in medicine for the production of disinfectants, and biocides materials, etc;

  • for transfer of hydrophilic substances into hydrophobic;

  • for the production of solar cells and fuel cells;

  • for the production of highly effective catalysts;

  • as concrete and paint modifiers;more info

  • in some other parts of machinery and industrial sectors (hardwearing and other coatings, cutting tools, lubricants, pigments, etc.)
