WebJan 10, 2013 · Fine powders of aluminates of rare-earth elements (REE) are obtained by wet combustion. The solid-phase synthesis of lanthanum-gadolinium aluminate is studied. It is shown that the desired phase can be obtained at temperatures to 750°C. WebJan 5, 2016 · However, enhancement of afterglow lifetime and brightness in SrAl2O4:Eu2+, Dy3+ phosphors remains a challenging task. Here, we have improved the afterglow characteristics in terms of persistence time and brightness by a systematic investigation of the composition of Eu-doped alkaline earth aluminate SrAl2O4:Eu2+, Dy3+ crystals.
WebAug 29, 2010 · The stability of synthetic REE-aluminate garnets irradiated by accelerated Kr 2+ ions and affected by alpha decay of 244 Cm (T 1/2 = 18.1 yr) has been studied. The dose of irradiation sufficient for the complete disordering of the aluminate garnet structure is 0.40–0.55 displacements per atom. Aluminium oxide (alumina) is amphoteric: it dissolves in both bases and acids. When dissolved in bases it forms hydroxyaluminate ions in the same way as aluminium hydroxide or aluminium salts. The hydroxyaluminate or hydrated aluminate can be precipitated and then calcined to produce anhydrous aluminates. … See more In chemistry, an aluminate is a compound containing an oxyanion of aluminium, such as sodium aluminate. In the naming of inorganic compounds, it is a suffix that indicates a polyatomic anion with a central aluminum atom.
