Kinetic analysis of vapor transfer of silicon by zinc sulfide
L. Yu. Udoeva, V. M. Chumarev, R. I. Gulyaeva
The article gives a theoretical and experimental substantiation of the possibility of vapor transfer of silicon by a sulfide carrier — zinc sulfide. It is shown that in terms of thermodynamics the high-temperature interaction of Si with ZnS has all the signs of a chemical transport reaction and occurs at sublimation temperatures of zinc sulfide - above 1330K. According to thermogravimetry (TG) data, processed by Ozawa – Flynn – Wall and ASTM methods of model-free kinetic analysis, the transfer of silicon in the form of volatile monosulfide can be considered with an acceptable approximation as one-step reaction with average values of the Eα and log A equaled 243.8 kJ/mole and 7.13 s–1, respectively. Temperature dependences calculated by autocatalysis and solid nucleation models correlate well with experimental data of thermal analysis and do not contradict the proposed mechanism of sequential transformation Si → SiS2 → SiS (gas), where the rate of formation of silicon disulfide plays a decisive role. The HSC 6.1 Chemistry (Outotec) program and the Netzsch Thermokinetics software were used in thermodynamic calculations and for kinetic analysis, respectivly. The obtained information will find application in the development of a new halogen-free method for producing of high-purity silicon.
Key words: silicon sulfides, vapor transfer reaction, thermodynamics, thermogravimetry, kinetic modeling.

Multi-layered high-temperature ceramics-refractory metal-based composite was developed by diffusion-bonding route. Strength parameters and fracture behaviour have been also defined. It has been found that processing parameters of a diffusion bonding under pressure allowed obtaining a dense composite with the values of open porosity and density П ≤ 2,2 % and
ρ = 7,0 – 7,4 g/cm3 respectively. A diffusion layer width 46 ± 10 mkm has been determined by scanning electron microscopy. Microstructure of a multi-layered composite containing Si-, B-, :Mo-, C-based compounds with different Si:B:Mo:C ratio and Mo foil with 70 or 200 mkm width has been studied. Preliminary thermal compatibility of a ceramic layer with a Mo foil has been defined. It has been demonstrated that for lower diffusion layer width it is essential to apply a thin barrier coating on a Mo foil before a diffusion bonding process. It has been shown that a composite possesses higher fracture toughness compared to monolithic ceramics of the same composition.
Keywords: multi-layered composite, pressing, spark-plasma sintering, microstructure, bending.

Research of structural and optical uniformity
of LiNbO3:ZnO crystals of different genesis

N. A. Teplyakova, S. M. Masloboeva, O. V. Makarova
Comparative analysis was carried out for congruent nominally pure LiNbO3 crystal and LiNbO3:ZnО ([ZnО] ~ 5.4 – 6.4 mol% in the melt) crystals of different genesis by photoinduced light scattering, laser conoscopy and X-ray (method of moments). Photorefractive properties, optical and structural uniformity were researched. It was established that LiNbO3:ZnО crystals obtained by direct solid phase doping possessed the best optical and structural uniformity, the less photorefractive sensitivity and high compositional uniformity along the polar axis. Crystals obtained by homogeneous doping are compositionally uniform though their optical and structural uniformity is worse than that of LiNbO3:ZnО crystals obtained by direct solid phase doping. Anomalies of conoscopic pictures were caused by the presence of charged structural defects in the LiNbO3:ZnО crystals and optical indicatrix distortion, which was induced by mechanical stresses and compositional inhomogeneity of crystals. High temperature annealing at short circuit of LiNbO3:ZnО crystals with high dopant concentration leads to healing of charged defects and general improvement of optical characteristics. It should be noted that distribution coefficient of LiNbO3:ZnО crystals grown by the, homogeneous doping method was significantly higher than one for these crystals obtained by direct solid phase doping method.
Keywords: lithium niobate single crystals, doping, photoinduced light scattering, laser conoscopy, X-ray analysis (method of moments).

with ultralow percolation threshold
I. Y. Klyuev, V. G. Shevchenko, A. M. Kuperman, V. I. Solodilov
We have got nanocomposites based on epoxy resin ED-20 and single walled carbon nanotubes (SWCNT) with high aspect ratio (l/d ~ 2500). Filler is doped into matrix due to high speed mixer without solvents. We have researched electrical characteristics produced composites as a function of the SWCNT concentration. It was experimentally established low percolation threshold, which indicates about low filler agglomeration in epoxy matrix. It was plotted dielectric permittivity and loss tangent as a function of the SWCNT concentration at wide frequency range. It was discovered, that for all dependences are characterized by the relaxation peak, which shift to high frequency range with growth filler concentration. The research of nanocomposite cleavages by scanning electron microscopy method showed uniform distribution SWCNT in matrix.

and cerium ions from sulphate solutions

Wei Moe Aung, E. A. Neskoromnaya, A. G. Tkachev
The adsorption of rare-earth elements (cerium and scandium) on initial and nanomodified activated carbons from sulfuric acid solutions simulating the composition of multi-metallic ore leaching solutions was investigated. The materials used to extract the cerium and scandium are considered. A composite sorbent based on coconut shell activated carbon, modified by carbon nanotubes, was proposed, and its structural and physical-chemical characteristics were described by scanning electron microscopy, thermogravimetry and Raman spectroscopy. The kinetic parameters of the cerium and scandium adsorption, as well as the optimum adsorption time — 125 min, adsorption rate constants, were determined. The adsorption capacity of the nanomodified material for cerium ions was 12.7 mg·g–1 and scandium — 5.9 mg·g–1. It was found that the cerium and scandium adsorption is driven by mixed diffusion, and the adsorption kinetics can also be satisfactorily described using the pseudo-first order model for both ions. Thus, both physical adsorption and chemical interactions between the ions and the adsorbent functional groups can be assumed to take place during the extraction of the Ce and Sc ions.

L. V. Morozova
The paper presents the results of research on the development of a liquid-phase method for the synthesis of highly dispersed aluminum oxide powders. It is shown that the use of freezing of freshly prepared Al(OH)3 at −25 °C (24 h) with its subsequent freeze drying makes it possible to obtain a powder-precursor of boehmite (AlOOH) with a specific surface area of 430 m2/g and unimodal particle size distribution (75 – 200 nm). The influence of the aluminum hydroxide freezing process on the temperature of phase transitions AlOOH → gamma-Al2O3 → gamma-Al2O3 → alfa-Al2O3 and texture characteristics of the synthesized powders gamma-Al2O3, alfa-Al2O3 (specific surface area, crystallite size, pore size distribution) was established. A chemically pure, nanocrystalline (~ 7 nm), gamma-Al2O3 powder with a mesoporous structure and a specific surface area of 258 m2/g is obtained. The dynamics of aluminum oxide sintering is studied, the possibility of obtaining high-density corundum nanoceramics at 1400 °C is shown.

T. V. Kusova (Gerasimova), I. A. Yamanovskaya, O. L. Evdokimova,
A. S. Kraev, A. V. Agafonov
Mesoporous structures based on titanium dioxide modified by iron ions were obtained via an effective and fast synthesis method based on the microwave-assisted polyol synthesis of titanium glycolate nanorods followed by the water treatment under microwave heating at 2.45 GHz. The obtained materials were characterized by scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS) analysis, X-ray diffraction analysis (XRD) and low-temperature nitrogen adsorption/desorption analysis. The effect of the iron ions concentration on the morphology, structure and photocatalytic activity of the composites was analyzed. In the photocatalytic decomposition reaction of the model dye Rhodamine B, it was found that the photocatalytic activity of titanium dioxide nanorods increases significantly at low level of iron ion doping (less than 3 %), which makes them promising as the materials for environmental photocatalysis.
Keywords: microwave synthesis, mesoporous, titanium dioxide, photocatalytic activity.

Study of structure and mechanical properties
of long-length metalware from D19-alloy produced
by continuous casting and deformation
of metal in solid-liquid state
A. M. Sergeeva, N. S. Lovizin, A. A. Sosnin
The new method of metal ware production in conditions of the combination of continuous casting and metal simultaneous deformation in solid-liquid state had been considered in this paper. The microstructure and mechanical properties of the obtained metal products from alloy D19 had been investigated. This method of continuous casting had been developed for production long-length metal wares having improved mechanical and performance properties. The processing of D19 alloy enhances the strength and ductility characteristics in the fabricated metal by using this technology. It was shown that the obtained metalwares had a fine-grained directional structure. The grain boundaries are uneven and wide and consisting of a plexus of dislocation loops and grids. This internal structure is formed immediately during the crystallization process and provides an increased mechanical characteristics. After leaving the crystallizer metalwares from D19 alloy have next mechanical characteristics: temporary tensile strength ≈ 290 MPa, yield strength ≈ 172 MPa, Brinell hardness ≈ 823 MPa, relative elongation 25 %. It has been established that the considered technology and implemented device allows for a short production cycle to obtain metalwares from aluminum alloys with high mechanical properties without additional processing. The disadvantages of the existing laboratory device are attributed to the presence on the surface of the workpiece periodic traces of movement of the moving walls of the crystallizer. However, this is a defect of the device, not technology, and it will be eliminated. The presented constructive solution is a small-sized installation that does not require large production areas. When implementing this process, there is no need for furnaces to maintain the temperature of the workpiece in the required range, for example, in accordance with the requirements of the rolling process.
Keywords: aluminum alloys, metal deformation in solid-liquid state, microstructure, mechanical properties, crystallization, continuous casting.
