Erbium Cube

Erbium is a chemical element with the symbol Er and atomic number 68. At present, this form of rare earth metal cube is very rare, and it is worth collecting from both metal and form.

Similar to Holmium, Erbium is also used to make lasers. Its oxides can be added to zircon jewelry in trace amounts, giving it a purple color, which can be added to porcelain enamel to obtain a pink glaze.

When the buyer saves, please pay attention to waterproof and acid-proof, try to store the rare earth cube in the dry and oxygen-deficient container to prevent oxidation. When we deliver, it will be packed in a vacuum bag.
