Nanowires have reached to the market

  • Comparative electromechanical characteristics of a new nanostructured material based on Cu-Nb (according to the data of "VNIINM" The AA Bochvar)
  • Comparative electromechanical characteristics of a new nanostructured material based on Cu-Nb (according to the data of "VNIINM" The AA Bochvar)

A week ago, in the NPP "Nanoelektro", a joint project company "RUSNANO" and VNIINM. Bochvar, began commercial production of innovative composite materials based on copper-niobium alloys with the so-called dispersion of nanometer level structure, combining high conductivity (up to 60-75% of the electrical conductivity of high-purity copper), and the strength of steel (1200-1500 MPa , 4-5 times stronger than copper). At the same time, wire parameters resulting alloy has a fatigue strength on the order of greater than similar properties of the same copper wire.

The work VNIINM, where he received most of the materials and alloys used in nuclear weapons now, and the nuclear energy industry, nano wires we wrote seven years ago (see "The heavy-duty, and the superconducting", «Expert» № 37 in 2005). R &D on the production of a superconductor in the early 1980s were initiated by the Kurchatov Institute, when it took up the development of high-power pulsed magnets, which can create ultra-high magnetic field intensity with values above 60 tesla. Alloys are usually applied to the conductors of the windings of such magnets just kept passing during their work huge currents in the tens of thousands of amperes. First, on the creation of materials to work with such currents experimented in the school, but then handed over developments in the industry profile Material Science VNIINM, who had an excellent addition to testing and experimental metal base. Here, the work on the creation of a material with almost ideal for demanding electrical device characteristics was carried out under the supervision of Doctor of Technical Sciences Victor Pantsyrny, now the Director for Research and Technological Development "Nanoelektro." If Kurchatov tried to introduce into the structure of copper inclusions micron dimension, the group managed to get Pantsyrny composite with the inclusion of niobium particles forming intertwined ribbons with thickness of 6-10 nanometers, which are fastened to the end of the copper lattice filler, providing its high strength, and at the same time do not hinder the movement of electrons.

While the path to commercial release was not close, "bochvarovtsy" before reaching out to "RUSNANO" managed to organize a pilot plant and carried out many contracts for the manufacture and supply of lots of expensive though, but the high-wire nanocomposite for research centers and companies around the world. Deal with "RUSNANO" in 2010 and the subsequent co-financing of the project goskoporatsiey VNIINM included now in rosatomovsky fuel elements, amounting to about half a billion rubles accelerated the process of commercialization. Power "Nanoelektro" will gradually increase, and by 2014 it is planned to produce up to 50 tons of composite materials in the year, and later — to reach a large-scale production, which will cover 15% of the global demand for heavy-duty electrical equipment. It is projected that by 2015, only the Russian market of such composites can exceed $ 33 million (58.3 tons) — almost 5% of the world market. The main consumers of heavy-duty wire will be aviation, aerospace, high-speed rail, nuclear and thermal power industry — an industry where there are high demands on the reliability of electronic and electrical systems, as well as research centers for the study of magnetic fields of high induction.
