Тип записи:Публикация, Synthesis and X-Ray Analysis of Complex Ferrites(Trans Tech Publications, 2017-07-01); ; ; Ferrite with mixed complex oxides BiNaFe2O5, BiKFe2O5 was synthesized by high temperature solid state reaction. The structure of the ferrites, type of syngony, parameters of the unit cells, radiographic and pycnometric densities were determined by X-ray phase analysis for a first time: BiNaFe2O5 – а=5,577, с=13,86 Å, γ=120º, Vun.cell. = 373,9 Å3, Z=4, ρrad.= 7,5262 г/см3, ρpicn.=7,5271 г/см3, BiKFe2O5 –а=5,545, с=13,65 Å, γ=120º, Vun.cell.= 363,45Å3, Z=6, ρrad.= 8,0367, ρpicn.=8,0375 г/см3. A comparative analysis of the relationship between crystal lattice parameters with parameters of the crystal lattice of initial oxides and complex ferrites has been performed. Research dependence of the magnetic moment of the complex ferrite BiNaFe2O5 of the applied magnetic field at a constant temperature T = 6.1405 K showed a paramagnetic shift in the structure.Цитирования (OpenAlex) 3Цитирования (OpenCitations) 3 - Некоторые метрики заблокированы вашиминастройками согласия
Тип записи:Публикация, Synthesis and X-ray analysis of complex ferrite YbBiNaFe2O6,5(Al-Farabi Kazakh National University, 2017-06-30); ; The complex oxide phase of the composition YbBiNaFe2O6,5 was synthesized by the high-temperature solid-phase reaction. X-ray diffraction analysis was used to study the structure for the first time; the type of syngony, unit cell parameters, X-ray diffraction and pycnometric densities were determined. X-ray diffraction was carried out by homology method from the initial fluorite structure δBi2O3. The method of least squares refined the parameters of the crystal lattice. The parameters of the orthorhombic lattice of complex mixed ferrite at the value of the number of formula units Z=4 are: a=5.2319, в=5.2186, с=7.5702 Å. The correctness of the results of the X-ray diffraction of complex mixed ferrite was confirmed by the good agreement between the experimental and calculated values of the inverse squares of the interplanar distances (104/d2). Satisfactory consistency of the values of the X-ray and pycnometric densities, ρrad = 8.335, ρpik = 8.328 g/cm3, proves the correctness of the results of the experiment. A comparative analysis of the interrelation between the parameters of the crystal lattice and the parameters of the crystal lattices of the initial oxide δBi2O3. The analysis shows the values of the parameters “a” and “c” are in satisfactory agreement with the parameters of the crystal lattice δBi2O3, the parameter “c” is distorted from the value of the parameter “a” on √2. - Некоторые метрики заблокированы вашиминастройками согласия

Тип записи:Публикация, SYNTHESIS AND X-RAY DIFFRACTION STUDY OF THE CHROMITE-MANGANITESIn this work synthesized new chromite-manganite phases using sol-gel method and their composition was studied by X-ray method. Chromium oxide, manganese oxide, yttrium oxide, metal carbonates, citric acid and glycerin were used as starting materials. It is shown that the use of citric acid and glycerol as precipitant, giving a positive effect to monophase samples. Precipitate was subjected to homogenizing roast in the temperature range from 600 to 1100°C, reaching the level of sintering samples were controlled by the basis of X-ray diffraction profiles. All the X-ray reflection lines have been successfully indexed according to the orthorhombic perovskite structure with space group: Pbnm (62) and with the following parameters: Y(1-x)MgCr0,5Mn0,5O3,(x≈0,7) –а=5.557, b=7.515, с=5.252 A, Z = 4; Y(1-x)BaCr0,5Mn0,5O3, (x≈0,7) –а=9.102, b=5.533, с=7.330 A, Z = 4; Y(1-x)SrCr0,5Mn0,5O3, (x≈0,7) –а=7.109, b=7.436, с=6.756 A, Z = 4.
