Abstract—We have examined the feasibility of mechanochemically stimulated thermal synthesis of lithium monoaluminates from a boehmite + lithium carbonate mixture with the use of a semicommercial scale ball mill. The effect of mechanical pretreatment of the mixture of boehmite and lithium carbonate on the solid-state reaction between them has been s...

Abstract—We have demonstrated two processes for the synthesis of zinc antimonide powder using rapid melt cooling: melt spinning and cooling in a liquid. The elemental and phase compositions and surface morphology of hot-pressed undoped and 3 wt % In-doped β-Zn4Sb3 samples have been studied by scanning electron microscopy, X-ray diffraction, and opt...

Abstract—Bi4–xNdxTi3O12 (x = 0.4, 0.8, 1.2, 1.6) bismuth neodymium titanate solid solutions have been prepared by solid-state reactions, via firing of mixtures of their constituent oxides in air at temperatures from 1003 to 1323 K. The crystal structure of the synthesized phases has been determined by X-ray diffraction. The results demonstrate that...

Abstract—The Y0.95Gd0.05PO4 phosphate with the xenotime structure has been synthesized in powder form and as ceramics. Ceramics with a relative density of ~99% have been produced by spark plasma sintering. The sintering temperature was 1140°C and the sintering time was ~18 min, without isothermal holding. We have assessed the radiation resistance o...

Abstract—CdSe layers having high photosensitivity (photocurrent to dark current ratio of 6.2 × 104) and an extremely low carrier concentration (9 × 1011 cm–3) have been grown on muscovite mica by thermal evaporation in a quasi-closed system. These results are of interest for producing materials for position-sensitive semiconductor photodetectors ba...

Abstract—Surface modification of GaAs in sulfur vapor by different procedures and subsequent annealing and thermal oxidation have an advantageous effect on the properties of heterostructures, ensuring binding of the constituent components of the substrate and the formation of films with a uniform surface, without well-defined defects. The approache...

Abstract—The DyGaTi2O7 and EuGaTi2O7 titanates have been prepared by solid-state reactions in a starting mixture of Dy2O3 (Eu2O3), Ga2O3, and TiO2 via firing in air at temperatures of 1273 and 1573 K, and their crystal structure has been studied by X-ray diffraction. Their high-temperature heat capacity (350–1000 K) has been determined by different...

Abstract—We have studied the properties of KDB-5 silicon diffusion-doped with manganese in the temperature range 1100–1300°C. The results demonstrate that raising the diffusion temperature in the range 1175–1300°C leads to a decrease in the concentration of electrically active manganese atoms, so that at t = 1300°C their concentration becomes consi...
