Acid-resistant material is obtained on the basis of metallurgy wastes ― clay part of «tails» of gravity of zircon-ilmenite ores, used as clay binder and ferrochromic aluminothermic slag, used as a repellent without using natural traditional materials. It has been found that the introduction of ferrochromic aluminothermic slag into the ceramic compositions contributes to the formation of highly refractory minerals (corundum, magnesia spinel, chromium oxide, bonite and mayenite), which increase chemical, physical and mechanical indices at a firing temperature of 1300 °C acid stops.
耐酸材料是在冶金废料--锆钛铁矿重力 "尾矿 "中的粘土部分（用作粘土粘合剂）和铁铬铝熔渣（用作驱避剂）--的基础上获得的，无需使用天然传统材料。研究发现，在陶瓷成分中加入铁铬铝熔渣有助于形成高耐火性矿物（刚玉、镁尖晶石、氧化铬、锰铝铁矿和马来铁矿），在 1300 °C 的烧制温度下，这些矿物会增加化学、物理和机械指数。

The features of the construction of a computational algorithm for calculating circular suction sockets in the conditions of an incoming flow by the method of discrete vortex rings are considered. Flow patterns are given at different ratios of the incoming and intake air flow velocities. The dependences of the characteristic sizes of vortex zones arising at the inlet to the suction-sockets on the velocity of the incoming flow, the length and angle of inclination of the socket are determined. Expressions are obtained for the critical velocity of the incoming flow, at which the flow separation mode for the first vortex zone changes from separation inside the bell to separation outside it. The obtained results can be useful for the construction of local suction systems, profiled according to the found outlines of vortex zones.

Premature decommissioning of steel-teeming ladle lining due to critical localized damage, whichi significantly reduces the functional properties of the lining, is one of the most acute problems in modern metallurgy. The main type of products used for steel-teeming ladle lining is periclase-carbon. In order to improve corrosion resistance and resistance to thermomechanical loads, additional additives, such as spinel, and high alumina CMA cement, are introduced into the periclase-carbon products. In this paper, the effect of calcium aluminate-based additive on the properties of periclasecarbon refractories is investigated. It is assumed that there is a potential for the formation of magnesium aluminate spinel (MA) in periclase-carbon products with calcium-aluminate additives during heat treatment. Fused periclase was used as the raw material, the carbon component was represented by natural flake graphite in an amount of 10 wt% and a combined binder. An additive based on calcium aluminates was introduced, with a fractional size from 0 to 3 mm, while the amount of main fractions of fused periclase was reduced by the corresponding amount of the additive introduced. The compressive strength, apparent porosity, and bending strength values before and after coking firing were analyzed. The thermal coefficient of linear expansion, phase composition and microstructure of the products were also investigated.

The article considers a method for activating cement hardening processes using nanomaterials due to the magnitude of their surface energy: when injected into concrete, nanoparticles dump it due to the desire to transition to a stable state. Such activity leads to a significant gain in strength, hardness and the production of high-strength concrete. It is shown that such an effect can be achieved by surface impregnation of concrete with sols (colloidal solutions) based on SiO2 nanoparticles. It is advisable to start impregnation from the third day of hardening under normal conditions. At this age, the main heat of the cement's own exothermic hardening reaction has already been released into the environment, and the introduction of additional energy will not cause a shift in equilibrium towards slowing down the hardening processes in accordance with the Le-Chatelier principle. The results of physico-chemical studies of concrete after hardening, explaining this effect, are presented.

Structural changes in cerium dioxide, when heated in vacuum in the range of 25‒1600 °C, in air in the range of 25‒1500 °C, and during successive annealing in the range of 1600‒2100 °C in air, followed by quenching in water, were studied. In the crystal lattice of CeO2‒х, the F → F1 phase transformation in vacuum proceeds in the range of 1100‒1600 °C; additionally, at 1200 °C, X-ray lines of the C-type Ce2O3 phase appear. The thermal expansion coefficient of phases of the fluorite type F and F1 in the range of 25‒1500 °C in air, as well as phases of the fluorite type F, F1 and type C Ce2O3 in the range of 25‒1600 °C are determined in vacuum and their dependence on the change in the oxygen content in the CeO2‒х crystal lattice was found. The kinetic conditions for reduction of cerium dioxide in vacuum and oxidation in air are different. The cubic structure of the fluorite type F CeO2‒х, when the samples are heated in air, is preserved up to 1800 °C with the content of anionic vacancies, at 1900 °C the transformation F → F1 occurs. The formation of loops, edge and screw dislocations in the structure of cerium dioxide grains after annealing of samples in the range of 1900‒2100 °C in air were discovered for the first time. The decomposition of the structure F1 into cerium oxide phases of types F and C proceeds at 2100 °C along the height and boundaries of screw dislocations. It was found that fragments of the C-type phase of cerium oxide are located on loops along the height of screw dislocations, which indicates the movement and evaporation of these fragments. When the samples are oxidized at 1600 °C in air, the black-colored C Ce2O3‒х phase in a gradient of different concentrations moves along certain trajectories to opposite ones. grain boundaries, abuts against dislocation loops, bends them, and oxidizes to phases F1 and F. In the structure of polycrystalline cerium dioxide, when heated in vacuum and in air, certain concentrations of defects control phase transformations.
在 CeO2-х 的晶格中，真空中的 F → F1 相变在 1100-1600 ℃ 范围内进行；此外，在 1200 ℃ 时，出现了 C 型 Ce2O3 相的 X 射线。测定了 25-1500 ℃ 空气中 F 型和 F1 型萤石相的热膨胀系数，以及 25-1600 ℃ 真空中 F 型、F1 型和 C 型 Ce2O3 相的热膨胀系数，并发现了它们与 CeO2-х 晶格中氧含量变化的关系。二氧化铈在真空中还原和在空气中氧化的动力学条件是不同的。当样品在空气中加热时，F 型 CeO2-х 萤石的立方结构在 1800 ℃ 时仍保持不变，并含有阴离子空位，在 1900 ℃ 时发生 F → F1 的转变。在 1900-2100 °C的空气中退火后，二氧化铈晶粒结构中形成了环状、边缘和螺旋位错，这是首次发现。在 2100 ℃ 时，结构 F1 沿着螺旋位错的高度和边界分解成 F 型和 C 型氧化铈相。研究发现，C 型氧化铈相的碎片位于沿螺旋位错高度的环上，这表明了这些碎片的移动和蒸发。当样品在 1600 °C 的空气中氧化时，不同浓度梯度的黑色 C Ce2O3-х 相沿着一定的轨迹向相反的轨迹移动，与位错环相邻，使位错环弯曲，并氧化成 F1 和 F 相。

Ceramic composites (1 ‒ x)ZrSiO4‒xZrO2 with low thermal conductivity were obtained by sintering nanosized powders in the range of 1000‒1300 °C in air. The fracture surface of ceramic samples after sintering at 1300 °C was investigated and their thermal behavior was studied by dilatometry. The chemical resistance of composites by leaching in distilled water was evaluated. In the future, such ceramic composites can be used as matrices for the purpose of long-term, environmentally safe storage and subsequent final isolation from the environment of individual isotopes of actinide-rare earth fraction of high-level waste (HLW).
