Phases of Anionic Ordering in Elpasolite Structures (Ordered Perovskites)
The 108 dissymmetric phases were obtained as a result of X anions ordering in elpasolite structure A2BB ′ X6 (ordered perovskite) using group theoretical methods. The critical order parameters which transform according to ...
Nanodispersed Mg-based Powders Received in a Hydrogen-argon Plasma Flow and Estimation of their Application Prospects as Hydrogen Storage Materials.
Nanodispersed powders, consisting of Mg, Mg and Ni, Mg and Pd, were synthesized in a water-cooled chamber in a hydrogen-helium mixture at atmospheric pressure. Plasma generation was carried out in HF arc discharge in an ...
Nanodispersed powders of Fe-Ni particles with carbon shell
The initial carbon condensate containing nickel-iron nanoparticles with a graphite conversion was syn- thesized in the high-frequency carbon-helium arc plasma at ambient pressure. The nickel-iron particles were extracted ...
Phase Velocities of Ultrasound Waves and Elastic Modules in the IIb Type Synthetic Diamond Single Crystal
First the results of experimental studies on the propagation of bulk acoustic waves (30–120 MHz) in the IIb type synthetic diamond single crystal have been presented in comparison with the appropriate data in the IIa type ...
