Influence of the Activation Time on Parameters of a Graphite Structure
Abstract—The structure of natural crystalline and cryptocrystalline graphites from deposits of Krasnoyarsk krai is investigated by means of XXray structural analysis using a D8 Advance diffractometer (Bruker, Germany). ...
Magnetic Properties and Critical Current of Superconducting Nanocomposites (1 − x)YBa2Cu3O7−δ + xCuO
The aim of this paper was to study the effect of nanoscale inclusions of CuO as the second ingredient of composites on transport properties of superconducting YBa2Cu3O7 polycrystals. The samples of YBa2Cu3O7−δ with different ...
Investigation of the residual stresses effect on the magnetic properties of CuO nanoparticles synthesized in a low-pressure arc discharge plasma
The laws governing the formation of residual stresses in copper oxide nanoparticles in the process of their direct plasma-chemical synthesis in a low-pressure arc discharge plasma are studied. Correlation dependences of ...
Investigation of the nanocomposite material YBa2Cu3O7−δ + ZrO2 as a resistive superconducting fault-current limiter
The effects of nanoscale inclusions ZrO2 as the second component of the composites on the magnetic and transport properties of superconducting polycrystals YBa2Cu3O7-δ are studied. Samples of YBa2Cu3O7-δ with different ...
WETTABILITY OF ACTIVATED BY VARIOUS MEANS GRAPHITE BY WATER–BASED SYSTEMS
The formation of a high-quality casting surface is a complex process, determined by the nature of an alloy filling, heating the mold, physicochemical and mechanical interaction of the melt with the atmosphere of the mold, ...
