Nano alloys should become the basis for the manufacture of new materials

Chemists from the University of Syracuse have developed a method for the synthesis of stainless steel nanomaterials. They believe that their discovery can change the materials that are used in the production of gas and manufacture lithium-ion batteries, due to their unique chemical stability.

Scientists came to the conclusion that metals, as a rule, with the size of 2 to 50 nanometers, have unique properties, including a high reactionary ability. Currently, scientists have conducted many experiments of chemical approaches to the possibility of managing reactions in which metal ions form alloys at the nano -level. The statement says that "we have developed a new synthetic path to creating an internal microstructure of nanomaterials.

The process begins with the preliminary synthesis of nanoparticles of the iron nucleus, after its crystalline form, thin shells of chromium are added. When the core and the membrane of the nanoparticles are exposed to high temperatures, iron and chrome pass the stage of diffusion into each other, forming an iron-chromium alloy similar to some forms of stainless steel.

Scientists said: “We found that nanoparticles have unique behavior during oxidation. The thin oxide shell of the iron-chromium, leaves behind the non-oxidized iron core. The fact that there is an emptiness in the forms that share the core from the shell." They added that "most of the alloys are difficult to make at the nano-level due Other specific conditions that are necessary to create new materials, but still the first steps in this direction have already been taken. ”
