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, Магнитные свойства композита частиц DyMn-=SUB=-2-=/SUB=-O-=SUB=-5-=/SUB=--Mn-=SUB=-3-=/SUB=-O-=SUB=-4-=/SUB=-(Ioffe Institute, 2020-12-15); ; ; ; A. T. KezdikbaevaThe paper presents the results of the experimental studies of magnetic and resonance properties of the DyMn2O5 – Mn3O4 particles composite. There are two magnetic transitions at temperatures T1 65 K and T2 230 K. T1 differs from the transition temperatures for the initial materials, and this fact is associated with the interparticle interaction. T2 corresponds to the impurity phase DyMnO3 (1 at.%). Three peaks of microwave absorption are observed in the magnetic resonance spectrum, which is explained in the framework of the model of a two-phase system in magnetic relation. One resonance is attributed to Mn3O4 and the other two peaks refer to the ensemble of strongly anisotropic DyMn2O5 particles with a random distribution of anisotropy axes.

Тип записи:Публикация, Selecting the rational parameters for restoring filtration characteristics of ores during borehole mining of uranium depositst(2022-09-30); Purpose. The research purpose is to increase the efficiency of borehole uranium mining by selecting special decolmating solutions and rational parameters of the technology for influencing the seam near-filter zone of geotechnological boreholes, as well as improving the filtration characteristics of the seam, depending on the mineralogical composition of ores and the structure of sediment-forming materials. Methods. The method of X-ray phase analysis was used to study the powders. The core material samples were studied on transparent sections using a LEICA DM 2500 P microscope. The content of the elemental composition of the ores and host rocks in the samples of the productive horizon was controlled using an atomic emission spectrometer. Findings. Based on the research results, quantitative-qualitative characteristics of the host rocks in the productive horizon, sedimentary formations from technological boreholes have been determined, revealing various levels in the productive horizon. It has been found that in the Campanian horizon boreholes, ores have a complex structure and multicomponent sedimentary formations, representing a mixture of sediments of mechanical-chemical origin. Originality. The results of quantitative-qualitative, microscopic, thermal research methods of the characteristics of ore-bearing rocks from various horizons at the Syr Darya depression uranium deposit have been studied and comparatively analyzed. The sedimentary formations of technological boreholes in the productive Santonian, Maastrichtian, Campanian horizons of the Northern Kharasan field, Syr Darya depression, have also been sampled and studied. The choice of the most appropriate composition of chemical reagents for dissolution and prevention of sedimentary formation in porous media has been substan-tiated by the microscopic research method. Practical implications. A detailed study and comparative analysis of the characteristics of ores and host rocks in various productive horizons makes it possible to more accurately plan the mining of blocks, minimizing emerging risks. Using the developed combined technology for intensifying borehole uranium mining, it is possible to increase the efficiency of borehole uranium mining and reduce its operating costs. At the same time, the ecological and industrial safety of the work of intensi-fying the leaching uranium ores increases.Цитирования (OpenAlex) 9Цитирования (OpenCitations) 9
