Nickel

History
 
Nickel was opened by Frederick Kronstedt in 1751. Title received on behalf of gnome Nick, who put furtively this ore to miners. In 1804, nickel was received by Jeremiah Richter. He first described the metal. First, the metal is not used, because even small sulfur content made the metal fragile, but then it became magnesium alloy, which took away the oxygen and sulfur. Alloys with nickel-plated steel produced even in ancient China BC. The nickel content in them was 20%. Then it started to get into Europe. Here he became known as: ARGENTAN, German silver, nickel silver (new money).

Nowadays

Devices for vacuum equipment makes from the nickel: light bulbs, wire holder, enter the grid, anodes, screens and cores for oxide cathodes and some other parts, as well as the expansion of nickel quite small. Coins of nickel-silver released so far. In the early 20th century has been opened yet another alloy: Nickel and copper, known as Monel metal. It has a chemical resistance, shiny mechanical properties and relative cheapness. More than half of nickel goes to smelte chrome-nickel construction and nickel alloys. Karbonil Nickel is used in many reactions.
