Characteristic

Nickel monoxide, an oxide of nickel, has the chemical formula NiO, where nickel has an oxidation state of +2.Since the substance is green powder under normal conditions, it is also called green nickel oxide, which is different from the black nickel oxide whose main component is nickel trioxide.Nickel monoxide is widely used in the ceramic and glass industries to make semiconductor thin films and as a catalyst for the oxidation of organic compounds.

Application

1. It is used as a sealing agent and coloring agent for enamel, and as a pigment for ceramics and glass.In the magnetic material production used in the production of nickel and zinc ferrite, and used in the production of nickel salt raw materials, nickel catalyst, and used in metallurgy, picture tube applications.Used as electronic component material, catalyst, enamel coating and battery material.

2. NiO can be used to reduce nickel elemental, but it should not be used to reduce NiO without protection. This is because Ni and CO react to produce highly toxic and volatile nickel tetracharbonyl Ni(CO)4, which is difficult to detoxify and prone to danger.

NiO is usually reduced with a safer reducing agent such as H2

NiO+H2== high temperature ==Ni+H2O 

3. Used for making nickel salts, ceramics, glass, catalysts, magnetic materials, etc.

4. Used as electronic component material and battery material.
