  • Crystallization of sodium perrhenate from NaReO4–H2O ...

    Crystallization of sodium perrhenate (NaReO 4) from aqueous solution was studied by means of laboratory scale experiments at 298 K. NaReO 4 has a very high solubility in aqueous solution (> 1130 g/L at 298 K) so crystallization was induced by the addition of ethanol (drowning-out crystallization process). This resulted in well crystalline NaReO 4 particles which required less energy and water ...


  • Rubidium - Wikipedia

    Rubidium cannot be stored under atmospheric oxygen, as a highly exothermic reaction will ensue, sometimes even resulting in the metal catching fire. Rubidium is the first alkali metal in the group to have a density higher than water, so it sinks, unlike the metals above it in the group.

  • Rubidium oxide - Wikipedia

    Rubidium oxide is the chemical compound with the formula Rb 2 O.Rubidium oxide is highly reactive towards water, and therefore it would not be expected to occur naturally. The rubidium content in minerals is often calculated and quoted in terms of Rb 2 O. In reality, the rubidium is typically present as a component of (actually, an impurity in) silicate or aluminosilicate.
