In this study, transparent oxyfluoride glass-ceramics (GCs) with NaLaF4 nanocrystals (NCs) were prepared by the sol–gel method for first time. Three different molar ratios of La(CH3COO)3/Na(CH3COO) used to obtain GCs, which sintered at 450, 550 and 650 °C 1 min. X-ray diffraction (XRD) was employed follow evolution xerogel during heat treatments study crystal growth three temperatures. all case...

Substituting fluorine for oxygen in niobium fluoride results a tuneable change from metallic to half-metallic conduction. This behaviour can also be switched using moderate applied pressure.

In the semiconductor manufacturing process, inner walls of equipment are coated with yttrium-based oxides for etch resistance against plasma exposure. Yttrium oxyfluoride (YOF) particle synthesis and coating methods have been actively studied owing to their high erosion compared Y2O3 Al2O3. Owing formation a rough porous layer by thermal spray-coating, disintegrates, as etching process has cond...

Abstract The production of the artificial 51 Cr neutrino source with activity > 3 MCi for experiment BEST is presented. This procedure consisted making a 50 target and irradiating it thermal neutrons in nuclear reactor SM-3. form disks thickness 4 mm diameter 84 88 included enrichment (to 96.5% Cr) natural chromium oxyfluoride by gas centrifugation, electrolytic reduction refining metallic c...
