The nickel oxide (Ⅱ) nickel oxide for the green powder solids. Is a kind of common inorganic compounds, bivalent nickel oxide, chemical formula for NiO, green powder, widely used in life, is also used for preparing high purity (> 99.98% nickel). This product is harmful to human health, the need to take care of the protection when contacting, the risk that the human body may have carcinogenic to sensitization.

It is used as a enamel and colorant, ceramic and glass pigment. It is used in the production of magnetic materials to produce nickel-zinc ferrite, as well as to make nickel salt raw materials, nickel catalysts and applications in metallurgical and imaging tubes. It is used as electronic component material, catalyst, enamel coating and battery material. [2]
2, NiO can be used for the reduction of nickel to be obtained, but notice must not be under the condition of unprotected use CO reduction NiO, this is because Ni and CO in response to generate toxic volatile carbonyl nickel four Ni (CO) 4, it is difficult to detoxify, easy to produce risk.
