Abstract |
The research is devoted to solving the problem of regulating the porosity parameters during the
manufacturing process under magnetic field conditions. The process of synthesizing magnetic nanocomponents based
on a mixture of divalent and trivalent iron oxides was given. The use of nanocomponents allowed for improving the
conditions for creating porous materials. A device with adjustable magnetic induction was developed to produce porous
materials in a magnetic field. The study of the porous material’s structure with the nanopowder content in the magnetic
field conditions showed a clear dependence of the structure on the magnetic parameters. When the content of
nanocomponents increased to 0.3 %, and the magnetic field induction increased to 2.5 mT, the dispersion of pore sizes
decreased by 8–10 times, the density of pores – increased by 15–20 times, and the average diameter of pores – decreased
by 12–15 times. Mathematical dependencies that determine the porosity parameters for different values of the magnetic
nanopowder content and the level of magnetic induction in the ring electromagnet were proposed. The obtained
dependencies allowed for assigning the level of magnetic technological parameters to ensure the given porosity
parameters. The developed methods of magnetic technology for creating porous materials can increase the quality and
ensure the required porosity level. |
