Finely-dispersed phosphors of Y 2 O 3 :Eu and Al 5 12 have been synthesized with the help Pechini method self-propagating high-temperature synthesis (SHS). During on basis carried out size crystallites increases enlargement concentration yttrium, but it decreases when SHS is applied. The structure (YAG) strongly amorphized. This fact agrees data XRD prevalence band λ max = 613 nm in spectra this phosphor. yttrium promotes amorphisation aluminum garnet decrease a crystal phase content. sample...
A technology, that allows production effective x-ray luminescent phosphors Zn 3 (PO 4 ) 2 :Mn 2+ with nanosized particles from the water solution by sol-gel method, and directional regulated their luminescence color green to red was developed. X-ray intensity spectra, phase structure, surface properties of synthesized samples depending on synthesis conditions studied. The which allow obtain according demands for luminophores medical assignment were determined.
The article presents the results on development of core-shell powders for additive manufacturing articles underground construction. Core-shell were obtained via advanced technologies involving gas (iodide) transport plating ceramic and carbon materials with metal nanocoatings to improve target performances (wear- corrosion resistance, etc.) as well 3D simulation preparation triply periodic minimal surface (TPMS) structures specific shapes, including Schoen Gyroid Schwarz Diamond.

This approach provides the extension application areas for such to some conditions where larger particles obtained by conventional co-precipitation...
Today 3D printing with ceramics is a promising direction in the development of additive technologies. In this work, we have developed technology for ceramic pastes based on aluminum oxide and wax, namely: an extruder was modeled manufactured, composition slip selected paste made. After choosing print parameters, test samples were printed: disk box. Since just one stages manufacturing products, then parameters drying sintering raw material. Drying products necessary to burn off excess amount...
Traditionally, the diamond-SiC-Si composite is obtained by silicification of pressing from diamond powders. During synthesis process, part undergoes transformation; as a result, final composition contains large proportion non-diamond phases. The paper examines possibility replacing with cheaper ceramic powders already in charge to reduce cost composite. Since formation occurs result reaction sintering, order ensure binding injected materials silicon, method applying layer pyrocarbon their...
The paper proposes and tests a method for increasing the modulus of elasticity diamond-carbide silicon composite by using core-shell diamond powders with pyrocarbon coating. It is shown that optimal temperature obtaining such coatings 900 °C. presence layer, 0.13 microns thick, on grains dispersion 250/200 smooth edges increases to 800 GPa.
