Allgemeine Beschreibung

Rubidium is a highly electropositive alkaline metal that can be obtained as a byproduct of refining lithium from lepidolite. It is used in photomultiplier tubes, laser cooling, atomic clock, photocell, nuclear medicine, and specialty glass.

Anwendung

Rubidium can be used as a starting material to synthesize rubidium hydrazinidoborane (RbN2H3BH3).
It can also be used as a reducing agent to synthesize reduced polycyclic aromatic hydrocarbons.

Questions

1–2 of 2 Questions  
  1. We are interested in purchasing a rubidium ingot (product no. 276332-1G). Could you please confirm if this is of natural abundance Rb or enriched 85Rb? I will provide all the necessary details for a quotation once I hear back from you. Thank you.

    1 answer
    1. This material is not specifically isolated or tested for the presence of specific isotopes. The naturally occurring ratio of each is approximately 72% stable isotope 85Rb, and 28% slightly radioactive 87Rb. This product is expected to have the same or a similar profile.

      Helpful?

  2. Are the Rubidium ingots (276332-1G) that you deliver in an ampule, stored in vacuum or in an inert gas?

    1 answer
    1. This product is packaged in sealed ampules under an Argon.
