Niobium Metal in 50mm (2x2in) Acrylic Cube for Element Collection

الوصف

Little wonder that exotic niobium should be used for jewelry when it rocks such beautiful skin hues. Like most other metals, pure niobium tends to oxidize in air. unlike most other metals, however, its oxides are particularly striking. By carefully heating the virgin metal at a precise speed and temperature just about any color can be achieved. You can even get iridescent effects such as this one where if looked dead on it is an intense indigo blue and from an angle it turns a shade of pink! A truly spectacular addition to your collection. Sample is a half-inch rod weighing approximately 20g. Purity is 99.9%.
