Abstract

The results of the influence of Ti⁴⁺ + Сo²⁺ ions on the magnetic properties of ferrites are presented. It is shown that the increase in the content of Со²⁺ + ions Ti⁴⁺ in the structure of spinel ferrites can be controlled to change as the values of magnetic permeability and temperature of the phase transition to the paramagnetic state. Magnetic and dielectric properties of ferrites are closely related to their chemical transformations during synthesis and temperature treatment. Temperature treatment, provides homogenization and formation of ceramic structure. The paper considers ferrite systems as phases of variable composition formed in the process of temperature treatment. Specific examples are given of modern ideas about the physic-chemical nature of the processes of synthesis of ceramics. The obtained samples are characterized by high density, micron size of crystallites, uniform distribution of alloying impurities, chemical homogeneity.
