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.

Тип записи:Публикация, SYNTHESIS AND X-RAY STUDY OF CHROMITE – GADOLINI FERRITE COMPOSITION Gd(1-Х)МeCr0.5Fe0.5O3( Me = Ca, Mg, x≈0,7)(2019-01-01); ; ; In the present work the X-ray study of the synthesized sol-gel by the method of new chromite-ferrites phases with the Gd(1-Х)МeCr0.5Fe0.5O3 (Me = Ca, Mg, x0,7) composition was presented.Chromium oxide, iron oxide, gadolinium oxide, metal carbonates, citric acid and glycerin were used as initial materials. It is shown that the use of citric acid and glycerin as a precipitator has a positive effect on monophase samples. Rainfall was subjected to homogenizing roasting in the temperature range 600-900°C. The reaching the level of sintering of samples was controlled by theX-ray diffraction profiles. The phase composition, crystal characteristics, type of the symmetry, unit cell parameters, radiographic and pycnometric densitieswere investigated by the method of X-ray phase analysis. The correctness of the X-ray diffraction results of the mixed ferrite complex was confirmed by a good agreement between the experimental and calculated values of the inverse values of the squares to the interplanar distances (104/d2). Satisfactory consistency of the X-ray values and pycnometric densities proves the correctness of the experimental results. The article presents results of synthesis and XRF studies of new complex oxide chromite–gadolinium ferrites doped with alkaline earth metals (Са, Mg). Results revealed the formation of samples with multifaceted structure. Developed oxide of the chromite – ferrite gadolinium has orthorhombic structure. References [1] Zvezdin A.K., Pyatakov A.P.
