A theoretical study of the film movement of the liquid phase on the surface of a permeable cylinder under the influence of the mass forces of gravity and the swirling gas flow has been carried out. The differential equations of motion were determined for the first time, the exact solutions for the velocity components provided adhesion film on the surface of permeable cylinder and equality of shear stresses at the interface were calculated to determine the thickness of the film and its pressure on the cylindrical surface. Theimpact of the outflow of the liquid phase on the hydrodynamics of film flow was analyzed. The resulting mathematical model allows taking into account the hydrodynamics of the film during the filtration, separation and heat exchange processes.

The chemical and phase composition of products formed by interaction of liquid glass with 20– 80% H3PO4is investigated. It is shown that the products of the synthesis include hydrated silicon and phosphorus containing phases. The silicon containing phase is a mixture of amorphous silica gel and nonstoichiometric sodium silicates. The phosphorus containing phase is sodium hydrophosphate Na2HPO4· 12H2O. It is established that the crystalline phase is formed irrespective of a mixing method and acid concentration. It is suggested that the cause of formation of acid salt of phosphoric acid even at a large excess of water glass is replacement of protons H + of silanol ?Si-OH-groups of silicic acid by cations of Na + and formation of sodium silicates which act as a connecting bridge between adjacent globules of the formed hydrogel.

The article focuses on the fact that the existing systems standard exergies chemical elements are not quite correct thermodynamically, the indicators that are negative values exergies nitrate salts and some other substances. The reason is that the three dominant components of the environment oxygen and nitrogen in the atmosphere and water in the ocean have thermodynamic probability of chemical interaction to form nitrate ion in the ocean. In this paper calculated the equilibrium contents of O2and N2in the atmosphere and the equilibrium concentration of NO3 – -ion in the ocean water, as calculated molar exergies O2and N2 and the air. Shown the air is the holder of the positive exergy and workability, and should not be regarded in exergy applications as ”gift resources”.

Electrodeposition of multicomponent nickel and/or cobalt alloys with nonmetallic inclusions from the complex electrolytes containing citric or malic acid was investigated. It has been confirmed that the decrease in the stability of metal complexes formed provides an increase in metal current efficiency. The use of malate complex electrolytes allows to diminish the effect of nickel and cobalt anomalous codeposition. Nickel-cobalt alloy electrodeposition fromcitrate electrolytes is accompanied by an overstoichiometric electrodeposition of nonmetallic components,phosphorus in particular.

Developed a mathematical description of the ash particulate material in the separation space roller mills. A mathematical model of the motion of particles in a swirling upward gas flow, for the first time takes into account the concentration of the solid phase. The dependence of the axial velocity of the particle on the velocity of the carrier medium at different concentrations of the solid phase. It is shown that at low solids content (1–5%) relative to the carrier gas environment with unrestricted conditions, the influenceof neighboring particles on the trajectory can be neglected.

Solid solutions of BiFeO3– SmCoO3were synthesized by a solid-state method. Peculiarities of the influence of isovalent substitution of Bi 3+ and Fe 3+ ions in BiFeO3by Sm 3+ , Co 3+ ions on the crystal structure and magnetic properties of Bi1–xSmxFe1–xCoxO3solid solutions are found. It is shown that the substitution 3-25% of the Bi 3+ , Fe 3+ ions in BiFe0O3by Sm 3+ , Co 3+ ions results in the gradual destruction of the antiferromagnetic and conception of ferromagnetic ordering. In this case replacing up to 10% of Sm 3+ and Co 3+ ions in SmCoO3by Bi 3+ and Fe 3+ ions leads to the stabilization of Co 3+ ions in a diamagnetic state.

A model for estimation of heat and mass transfer processes in the basins of the extracts of spent nuclear fuel from NPP reactor VVER-1200 with varying degrees of filling is presented. For the calculation of transport processes in the racks of basins of the extracts the porous body model is proposed, which allowed carrying out a model description of complex constructions. It is shown that excessive tight pack of “fresh” spent nuclear fuel can lead to a significant temperature rise of the spent nuclear fuel. According to the results of numerical simulation, the filling levels of spent nuclear fuel do not exceed 20% for “fresh”fuel.

The process and composition of heat treatment of products of galvanic slimes which have different qualitative and quantitative composition of chromophore determining components are studied depending on the heat treatment conditions. It is established that the heat treatment of the galvanic slimes under different oxygen concentrations in the gas phase and chromophore determining compounds leads to the formation of a number of phases of variable composition in the form of oxygen solid solution in different modifications of iron oxide ?magnetite Fe3O4, maghemite ?-Fe2O3and hematite ?-Fe2O3. It is shown that crystal structures of solids with well-defined arrangement of atoms retain stoichiometry only at a certain partial pressure of oxygen on the step of slime heat treatment. This pressure is a function of temperature. The formation of ferrite products determines the color of pigment-filler and content of water-soluble substances.

Solid solutions of BiFeO3– PrCoO3system were synthesized by means of the solid-state reactions method using bismuth ferrite, BiFeO3and praseodymium cobaltite, PrCoO3 precursors. The temperature-time synthesis regimes of the precursors and the solid solutions were selected. The crystal lattices parameters of the solid solutions of Bi1–xPrxFe1–xСоxО3composition (x= 0, 0.2, 0.5, 1) were determined. The possible mechanisms of formation of the solid solutions from the precursors were proposed.

In the Republic of Belarus a potential source of vanadium-containing secondary raw materials is vanadium-containing sludge generated by the combustion of fuel oil in the boiler units of power plants. Vanadium concentration there is ten times greater than its content in the traditional ore raw materials. The total number of vanadium-containing sludge on the territory of the Republic of Belarus for the beginning of 2012 wasdetermined. Methods of vanadium-containing compounds extraction from vanadium-containing sludge ThPS were developed with the use of hydrometallurgical method. The methods influence of the vanadium-containing compounds extraction from sludge of ThPS on their composition and amount of extraction was studied.
