FAQ

What is Ytterbium (CAS: 7440-64-4)?

Ytterbium is a silvery-white metallic chemical element with the symbol Yb and atomic number 70. It belongs to the lanthanide series and has CAS number 7440-64-4. Ytterbium is highly reactive and forms compounds with a +2 oxidation state.

What are the main uses of Ytterbium (CAS: 7440-64-4)?

Ytterbium is primarily used in the electronics industry for its electrical and magnetic properties. It is also found in glass manufacturing, as a colorant and opacifier. In scientific research, ytterbium is used as a dopant in lasers and as a neutron absorber in nuclear reactors.

Is Ytterbium (CAS: 7440-64-4) safe?

Ytterbium is generally considered safe when handled properly. It is not toxic but can cause skin irritation if it comes into contact with the skin. Proper safety measures include wearing gloves and protective clothing. Ytterbium should be stored away from moisture and other reactive metals.

How should Ytterbium (CAS: 7440-64-4) be stored?

Ytterbium should be stored in a dry and cool place, away from moisture and other reactive metals. It should be kept in a tightly sealed container to prevent oxidation. Exposure to air and light should be minimized to preserve its stability and reactivity.
