Russia plans to build a composite industry cluster, dedicated to the production of alumina nanofibers

According to Russian satellite news agency sputniknews, Russia’s Krasnoyarsk Territory plans to build a composite industry cluster.

The core of the industrial cluster will be the industrial production of alumina nanofibers (Nafen), which is the first to be launched globally. With alumina nanofibers, the properties of some materials can be improved.

The new material, Nafen, is an alumina nanofiber that is similar in size to carbon nanotubes. Alumina nanofibers are 10 nanometers in diameter and 5000 times thinner than human hair. At the same time, alumina nanofibers are uniformly distributed after mixing with other materials, which is superior to carbon nanotubes.

“In the process of producing carbon nanotubes, carbon nanotubes attract and entangle each other, and there is currently no way to separate them.” Stanislav Hartov, Senior Research Fellow, Krasnoyarsk Research Center, Siberian Branch of the Russian Academy of Sciences “The newsletter” said, “When the carbon nanotubes are added to the material, the obtained composite material becomes more uneven, and its strength characteristics are difficult to predict. Alumina nanofibers and carbon nanotubes composed of nanofibers Different, can be evenly dispersed.”

In addition, alumina nanofibers are superior in price to carbon nanotubes. It is expected that after industrial production, the price of 1 kilogram is about 60 euros, which is 100 times cheaper than carbon nanotubes.
