Research of physic-chemical properties
and structure of strongly doped LiNbO3: ZnО
([ZnO] ~ 4.02 – 8.91 mol.%) crystals

A. V. Kadetova,  I. V. Biryukova, O. V. Makarova


In LiNbO3:ZnО crystals grown from melts containing ~ 4.0 – 9.0 mol. % ZnO were researched evolution of structure, were detected lattice periods, were analyzed atom structure models. Raman spectroscopy and full-profile analysis of XRD patterns were used to obtain the results. Rise in ZnO concentration in the melt from 4.0 to ~ 6.99 mol. % leads to decrease in the unit cell volume of the crystals. Ongoing rise in ZnO concentration in the melt to ~ 7.8 mol. % results in increase of the unit cell volume of the crystals. Refinement of the profile characteristics of XRD patterns and structure characteristics of the researched crystal samples were made by Rietveld method using the software PdWin. All samples were considered single-phased taken into consideration absence of the intense bands coinciding with the lithium niobate bands. Zn2+ cations were detected to occupy Li sites (that are vacant in the congruent LiNbO3 crystal). At this Nb vacancies are absent. Zinc displaces all excess Nb atoms in Li sites In the sample grown from melt with ~ 6.12 mol. % ZnO. At this Li vacancies and electro neutrality stays the same in the sample. Thus anti-structure defects NbLi are absent in the crystal LiNbO3:ZnО (~ 6.12 mol. % ZnО in the melt). In LiNbO3:ZnО crystals with higher ZnO concentration anti-structure defects NbLi appear again. At this concentration of Zn in Li sites almost coincides with the one in the LiNbO3:ZnО crystal. Unit cell parameters are equal in crystals grown from melts with ~ 7.8 and ~ 6.76 mol. %. The biggest changes in the Raman spectra of the searched crystals are observed in: 200 – 300 cm–1, vibrations of cations located in oxygen octahedra ВО6 (В: Nb5+, Li+, Zn2+); 500 – 900 cm–1, vibrations of oxygen atoms in oxygen octahedra. This indicates a change in alteration order of intrinsic, doping cations and vacancies along the polar axis and deformation of oxygen octahedra during doping. Which corresponds to anisotropic expanding of oxygen octahedra along the polar axis in the crystals LiNbO3:ZnО.

Radiation hardening of structural cement-magnetite-serpentinite composite under gamma irradiation with increased dose

R. N. Yastrebinskii, G. G. Bondarenko, V. I. Pavlenko


On the basis of the studies carried out it has been shown that it is possible to obtain a structural radiation-protective composite material having high resistance to radiation-thermal loads. The material was obtained on the basis of a Portlandt cement, boroncontaining chrysotile, magnetite filler, plasticizing additives and metal fraction by vibro-packing method. The content of chemically bound water was at least 1.5 mas.%. Exposure to high doses of gamma irradiation leads to the formation in the cement- magnetiteserpentinite composite of the single-calcined ferrite CaFe2O4, which has high physical and X-ray density. Its formation leads to radiation hardening and an increase in the mechanical strength of the composite up to a dose of 10 MGy. When γ-irradiation of a protective composite with an absorbed dose was of 20 MGy the mechanical strength of the composite was reduced by only 4 – 5  %, as compared to the unirradiated sample.

 

Keywords: magnetite, boron-containing chrysotile, radiation protective composite, gamma irradiation, absorbed dose, radiation resistance, structure, calcium ferrite.

We investigated the effect of water-soluble polymer — chitosan succinamide — on surface activity such commonly used surfactants how anionic and non-ionic sodium dodecylsulfate TWEEN-80. It has been shown that the combined use of sodium dodecylsulfate and TWEEN-80 with chitosan succinamide increases the surface activity of the investigated surfactants.
 It was found that the association of chitosan succinamide with sodium dodecylsulfate or TWEEN-80 begins at concentrations an order of magnitude lower than the critical micelle concentration of studied surfactants. It have been showed the fact of reducing the dynamic viscosity of the solution of chitosan succinamide, and in the presence of ionic and nonionic surfactants, apparently due to the formation of polymer-colloid complexes. Teachings systems have a stabilizing effect on the membrane of red blood cells in a hypotonic stringent conditions, which may indicate a decrease in surfactants adverse effect on the skin.

N. S. Dymnikova, E. V. Erohina, A. P. Moryganov


The kinetics and stability of ultrafine particles of silver at the reduction of its salts in the extracts of bast fibers  were studied by optical spectroscopy and visual observations. The dependence of the dynamics of formation of nanoparticles from a quantitative yield of impurities in the extract was shown. It is found that the size of the formed nanoparticles (including the envelope of stabilizer) are in the range of 4 – 50 nm. The possibility of applying synthesized silver sols to provide antimicrobial activity to the textile materials from natural and synthetic fibers or stability to microbial degradation with minimal content in them nanoparticles (0.07 wt. %) were evaluated. Coefficient of nanocomposites stability to microbial degradation after long-term (10 – 14 days) of their contact with the soil microflora is over 90 %. In addition, modification of textile products with developed “Nanoteks” preparation will allow to increase the efficiency and environmental safety of the technology and finished products.

Influence of single-wall carbon nanotubes on mechanical  and deformation properties of butadiene – nitrile rubber

N. V. Shadrinov, A. R. Khaldeeva, L. V. Pavlova


The paper presents the results of a study of the properties of butadiene nitrile rubber filled by single-walled carbon nanotubes. There are two different ways of filling of single-walled carbon nanotubes into the rubber mixture are considered. The influence of carbon nanotubes on physical and mechanical properties, resistance to aggressive environments and abrasive wear, thermal properties and residual strain after compression are researched. It is shown that the filling of a small quantity of carbon nanotubes Tuball (less than 1 wt. %) in butadiene-nitrile rubber does not lead to change of physico-mechanical and the main technical properties. A significant increase in the strength characteristics is observed at the filling of 2.5 and 5.0 mas. % of Tuball. The effect of carbon nanotubes on the deformation properties of the nitrile rubber is studied by atomic force microscopy. Special device with a stretching mechanism compatible with atomic force microscope is developed and patented for study of deformation properties of the filled rubber. The change in the surface structure of filled rubber under deformation, namely the deformation of three dimensional reticulated structures formed by carbon nanotubes and the dependence of Poisson’s ratio and surface roughness on the degree of uniaxial stretching are shown. It is shown that with increase of deformation leads to increase of average surface roughness associated with the development of microcracks on the surface, and destruction of large defects of the coating to the smaller ones.

E. N. Tugolukov, Yu. А. Han


The actual problem of the organization with the use of new technologies for industrial production of the metal-metal oxide catalysts (for example, the composition of Co – Mo / Al2O3 – MgO) for the synthesis of carbon nanotubes was solved. The main groups of characteristics of catalytic systems that define their quality were identified and discussed. They are physico-mechanical properties (bulk density and tapped density, angle of repose, tapped and collapse), the degree of feedstock conversion (the proportion of loss of mass during heating and calcination), the catalyst activity (specific yield carbon nanotubes on the catalyst and specific surface area) and indirect indicators (pH aqueous suspension and the true density). Methods and modes of study selected parameters of the catalyst were experimentally proved and analytical equipment was recommended. A new control factor stage of the thermal decomposition of catalyst was identified. It is the specific consumption of dry air. Its effect on catalyst performance was shown. Experimentally determined necessary and sufficient for the specific consumption of the catalyst Co – Mo / Al2O3 – MgO, which allows to stabilize the quality indicators. It is equal to 55 kgair/kgcatalyst. Considered metrological approaches to the certification of the produced catalysts Co – Mo/Al2O3 – MgO that have helped to improve the quality of the catalyst, in conditions of real enterprise carbon nanotechnology (“NanoTechCenter” Ltd., Tambov, Russia). The relative divergence of the mass loss during annealing has been reduced from 110,0 up to 24, specific yield — from 64.9 to 8.5, specific surface area of nanotubes — from 45.6 to 15.4 %.

Synthesis of oxinitrides of aluminum from MоO3/Al/AlN mixtures by SHS-metallurgy methods

P. A. Miloserdov, V. I. Yukhvid, V. A. Gorshkov, M. I. Alymov


In the present study, the regularities of the autowave chemical conversion of the MoO3/Al/AlN mixture, the gravitational separation of its combustion products, formation of the composition and structure of the desired product (aminium oxynitride) are studied. It is shown that MoO3, Al and AlN mixtures are able to burn in wide ranges of reagent ratios. In general, the process includes 3 consecutive stages: stage 1 — combustion and chemical conversion of a mixture of MoO3, Al and AlN into a two-phase melt of final products (autowave synthesis); stage 2 is the gravitational separation of combustion products (metal and oxide phases), during which 2 layers are formed: the upper layer is made of “light” oxynitride (Al2O3-AlN) and the lower layer of the “heavy” intermetallic compound (Mo-Al); stage 3 — cooling and formation of the phase composition, the crystal structure of the metallic and oxide layers. It is established that a change in the aluminum content in the initial mixture with a constant nitride additive content significantly affects the combustion and autowave chemical conversion of the mixture, the phase composition and the structure of the desired product (aluminum oxynitride). Optimum compositions for the production of aluminum oxynitrides with a high nitrogen content (up to 6 – 9 % by weight) and an impurity content (Al7O3N5 and AlN) of less than 3 % by weight were determined. The obtained cast aluminum oxynitride and the method of its preparation are promising for the manufacture of highstrength transparent ceramics.

 

Keywords: transparent high-strength ceramics, aluminum oxynitride, SHS-metallurgy, combustion, chemical transformation, gravity separation, composition and structure.
