In the present work, structural, magnetic, and thermodynamic properties of ${\mathrm{Dy}}_{1\ensuremath{-}x}{\mathrm{Er}}_{x}{\mathrm{Ni}}_{2}$ $(x=0.25,\phantom{\rule{0.16em}{0ex}}0.5,\phantom{\rule{0.16em}{0ex}}0.75)$ Laves-phase intermetallics, being continuous solid solutions in ${\mathrm{DyNi}}_{2}\text{\ensuremath{-}}{\mathrm{ErNi}}_{2}$ system, synthesized by arc melting, are experimentally studied analyzed accordance with mutual substitution within rare-earth sublattice. The...
The chemical and mineral compositions of bauxite recovered from the Severoonezhsk Bauxite Mine (Arkhangelsk region, Russia) were studied by XRD, ICP-OES, TG/DSC, SEM, TEM, Mössbauer spectroscopy. iron-containing minerals bauxites found to comprise alumogoethite (α-Fe1–xAlxOOH), alumohematite (α-(Fe1–xAlx)2O3), alumoakaganeite (β-Fe1–xAlxO(OH,Cl)), chromite (FeCr2O4). efficiency Fe extraction HCl leaching was 82.5% at 100 °C, concentration 10%, solid/liquid ratio 1:10, process duration 60...
Iron contained in coal fly ash of the Ekibastuz power station is distributed between magnetite and hematite. XRD data showed that ~80 wt % iron ~20 The leaching from CFA by HCl was studied. It determined efficiency increased with increase hydrochloric acid concentration temperature. maximum extraction 52%. Aluminum mullite practically not leached. aluminum 3.7%. kinetics investigation process controlled chemical reaction diffusion steps, an activation energy 33.25 kJ·mol−1. a step 19.89...
Sandy grade alumina is a valuable intermediate material that mainly produced by the Bayer process and used for manufacturing primary metallic aluminum. Coal fly ash generated in coal-fired power plants as by-product of coal combustion consists submicron particles considered to be potentially hazardous technogenic waste. The present paper demonstrates Al-chloride solution obtained leaching can further processed obtain sandy alumina, which essentially suitable aluminum production. novel...
The modification of structural properties and magnetic behaviour the ErFe2−xAlx Laves phase intermetallic compounds have been studied while changing Al content in range 0.36 ≤ x 1.5. Powder X-ray diffraction study at room temperature showed formation cubic C15 structure, samples with < 0.75 1.4 2.0. For intermediate compositions 1.4, hexagonal C14 structure is observed. Magnetic magnetocaloric polycrystalline were investigated experimentally using heat capacity measurements. Curie TC...
This article presents data on shock waves effect the structure and critical current of superconducting MgB2 tapes. To generate waves, a plasma focus installation (PF) was used. The conductive characteristics tapes dependence intensity impact number pulses were studied. A distinct pattern change in currents transversal longitudinal magnetic fields range 2–9 T is studied at temperature 4.2 K. microstructure tape chemical composition its layer are original state after wave effect. Changes found...
