Purpose. To obtain ultra-thin nanocrystals of highly anisotropic hexagonal barium ferrite.
Application area. Chemical industry.
Advantages. In a number of output parameters, nanocrystalline ferrite powders exceed the best foreign analogues.
Description. Fundamentally new methods for obtaining ultra-thin nanocrystals of highly anisotropic hexagonal barium ferrite have been developed, which use elements of cryochemical and radiation-thermal technologies. magnetic state diagram (temperature-magnetic field-interparticle magnetic interaction parameter), which is designed to match the powder dispersion and magnetic stability of the particles.
