Glass bead doped with 0.05 mol% Chromium(VI) Ions – NEW!
Size about 10mm . Material: NaLaB:Cr
Nice glass bead. Each one handmade of Sodium lanthanum borate glass in our lab.
There is always an equilibrium of Cr6+ and a little of Cr3+ which results in this Yellowish green color.
Beautiful optical glass beads doped with metal ions.
Elaborately and individually manufactured by us in the laboratory from highly pure reagents.
Gorgeous beads showing the typical colors of different metal ions in different oxidation states.
They can be used for save demonstration of different colors of the metal compounds or just for collecting.
