SYNTHESIS AND PHYSICO – CHEMICAL CHARACTERISTICS OF COMPLEX FERRITE CrNaFe2O5

Abstract

Abstract: Introduction. The article discusses for the first time the synthesis, radiographic and electron
microscopic examination of CrNaFe2O5, synthesized using the high – temperature Sol-gel method. The
phase of complex ferrites was synthesized using Sol-Gel synthesis method at high temperature. Initially,
the structure of CrNaFe2O5 composite ferrite was researched by X-ray phase analysis and SEM, the
syngony type, elementary cell parameters, radiographic and pycnometric densities and elemental analysis
were defined: CrNaFe2O5 -а=5.0289, в= 5.0289, с=13.6938 Å , ρx-ray.= 5.327 g/sm3
, ρpycn.=5.331 g/sm3
. A
comparative analysis of the connection between the parameters of the Crystal cell of the initial materials
and of the obtained complex ferrites was carried out. Through a scanning electron microscope,
microsystems were taken from different parts of CrNaFe2O5 type crystallite, the elemental composition of
crystals was analyzed, and the general type of surface layer of complex ferrite was displayed. As a result,
the fact that the compound consists of a single phase, the clarity of its construction was determined by the
topography and chemical composition of the compound. Consequently, it was discovered that the newly
synthesized complex ferrites correspond to the formula CrNaFe2O5. The particles of the formed
compounds have a large size (between 200 µm, 20.0 µm and 5 µm). The results of the element analysis
show that the compound is compatible.
