Nickel arsenide refers to inorganic compounds composed of nickel and arsenic. Several forms exist including a monoarsenide with the chemical formula NiAs and another with the formula Ni5As2.[2] It is highly toxic and a known carcinogen.[3]
Occurrence
Nickel arsenide occurs in the following minerals:
Preparation
Nickel arsenide can be prepared by direct combination of the elements:[7]
- Ni(s) + As(s) → NiAs(s)
History
Nickel arsenide was one of the first compounds that revealed the toxicity of nickel. The damage to the miners' lungs was documented by Georgius Agricola in the 16th century: "kupfer-nickel" ores in the Schneeberg mines contained red-colored NiAs mineral originally mistaken for the copper ore, thus the German: kupfer (copper) in the name. The German: Nickel (demon) name was reflecting the damage it did to the health of the workers,[8] in addition to them being unable to extract any copper from this ore.
