Mandala #41 — Nb: Niobio (Niobium)

Element 41 · Nb · Niobio
Anodized spectral rainbow
The jewelry metal with a rainbow surface — superconducting at low temperatures, its anodized colors rival the peacock.

Niobium anodizes in every color of the rainbow depending on oxide thickness — it is used in artistic jewelry for this reason. Below 9.3K, it becomes superconducting. Niobium-titanium superconducting wire makes the electromagnets of MRI machines and particle accelerators.

50 Mandalas de Elementos Químicos — a sacred geometry digital art series where science and beauty converge. Each mandala's palette, pattern, and structure is inspired by the element's atomic character, crystal structure, reactivity, and visual identity.
