Boride nanoslick or nanowire is composed of borides of metals structure in the layer Anatoliy.

METHOD - 1 obtain nanolayers or nanowires is that any fiber or film (hereinafter "the Foundation") is deposited a layer of metal or boron, which is then deposited a layer of boron or metal, respectively, or on the basis of precipitates multiple alternating layers of metal and boron with a total thickness of not more nanoscale, which are then subjected to gradual heating to a temperature of 1500 degrees C (hereinafter - "the process of boriginal", see "encyclopedia of Chemical", "B", article "the Borides"). Thus there is a gradual reaction formation boride metal.

If the film or fiber is so heat-resistant that do not evaporate or do not decompose under the above-mentioned process (for example, corundum nanowire), they can remain in the structure. There will be a combined nanoprene or tubular composite nanowire.

It should be noted that the total thickness of the composition will be more nano, but the thickness of the boride layer tubular film will correspond to the nano range.

After the process is finished, the glass can be removed by heating and subsequent evaporation.

Example 2. On the corundum nanoplasma from the gas phase containing a halide of titanium and boron, is deposited a layer of boride titanium Anatoliy. Moreover, it is possible that they will be deposited on both sides of the film. And the resulting composition may be again applied the PSS is (or two layers on both sides) corundum, etc. Can get a "package" of alternating nanolayers with unpredictable until the property.
