30 Facts About Smaltite

What is Smaltite?

Smaltite is a fascinating mineral with a rich history and unique properties. Known for its metallic luster and cubic crystal structure, it has intrigued scientists and collectors alike. Let's dive into some intriguing facts about this mineral.

1. Smaltite is a cobalt arsenide mineral, primarily composed of cobalt and arsenic.
2. It often appears in shades of silver-white to steel-gray, giving it a distinctive metallic sheen.
3. Smaltite crystallizes in the isometric system, typically forming cubic or octahedral crystals.
4. This mineral is commonly found in hydrothermal veins, often associated with other cobalt and nickel minerals.
5. Smaltite has a Mohs hardness of 5.5, making it relatively hard but still susceptible to scratching by harder substances.
6. The name "smaltite" is derived from the German word "smaltin," which refers to cobalt ores used in blue pigments.
7. It was first described in 1758 by Swedish chemist Axel Fredrik Cronstedt, who is also credited with discovering nickel.
8. Smaltite is often found in the same geological environments as skutterudite, another cobalt arsenide mineral.
9. This mineral is an important source of cobalt, a metal used in various industrial applications, including batteries and superalloys.
10. Smaltite can be toxic due to its arsenic content, so handling it requires caution and proper safety measures.
