Nickel powder

Nickel is located in group 10 (VIII) and is the third element in the special triples (Fe, Co, Ni) of the first series of transition elements. Nickel is a hard, silvery white, malleable metal block or gray powder. Nickel powder is pyrophoric and can spontaneously ignite. It may react violently with titanium, ammonium nitrate, potassium perchlorate and hydrodicarboxylic acid. It is incompatible with acids, oxidants and sulfur. The chemical and physical properties of nickel, especially its magnetism, are similar to those of iron and cobalt. Some acids attack nickel, but it also provides good protection against air and sea water corrosion. This makes it very suitable for electroplating other metals to form a protective coating. Nickel is also an excellent alloy metal, especially iron, which can be used to make stainless steel and protective armor for military vehicles. It is extensible and can be drawn into lines. About a pound of nickel metal can be pulled to about 200 miles of thin wire.
