Researchers from the Tyumen State University (TSU) and the Tomsk Polytechnic University (TPU) have developed a method for utilizing carbon dioxide (CO2, which belongs to gases that create a greenhouse effect and destroy the Earth's ozone layer - note from the editors of www1.ru) and obtaining nano- and ultrafine powders of metal oxides.
According to the authors of the project, carbon dioxide was used as a working medium for the synthesis of metal oxides in a pulsed plasma arc discharge. The output was a powder, with which it is possible to create ceramic products in a spark plasma sintering installation.
The peculiarity of the method lies in the fact that in the process of powder production, 3 times more CO2 is processed than with other methods. The technology of Tyumen and Tomsk researchers can be used in various production processes and does not harm the environment with carbon dioxide emissions.
