The paper presents the experimental results of light radiation from Y2O3 ceramics caused by X-rays with energy up to 50 keV. The samples were made from commercial Y2O3 nanopowder by pressing and subsequent sintering in air at different temperatures from 1... see more

Tungsten heavy alloys are considered as two phase composites with 88 to 97 wt% tungsten interspersed in a matrix of relatively low melting elements such as nickel, iron and cobalt. The mechanical properties of these alloys are greatly influenced by the mi... see more

The results of studying the structure and phase composition of dispersed oxide inclusions of particles and coagulation of yttrium, aluminum, zirconium particles oxides, in a model system based on carbonyl iron. The observed oxide particles distribute... see more

The results of the concentration dependence analyzing of the inclusions elemental composition and the matrix to determine the comparative values of diffusion coefficients in disperse strengthening a-iron. Numerical simulation of two-dimensional data is al... see more

Synthesis and certification of lanthanum oxide extracted from monazite sand have been carried out. This research aimed to increase the added value of monazite sand and obtain the lanthanum oxide in-house certified reference material (CRM). Synthesis of la... see more

The present study was carried out in the botanical garden / department of biology /college of science in ALmustansiriyah University, Baghdad. During winter 2017 under natural environmental conditions in plastic house. The aim of this study was to evaluate... see more

Yttrium belongs to the rare earth elements and critical metals. Yttrium oxide is mostly used in fluoroscent lamps, production of electrodes, in electronic filters, lasers, superconductors and as additives in various titanium-aluminium materials to improve... see more
