About Nickel Oxide NiO :
Nickel oxide is an inorganic substance with a chemical formula of NiO and a molecular weight of 74.71.
What is NiO in chemistry? 
Nickel(II) oxide is the chemical compound with the formula NiO. It is the principal oxide of nickel. Nickel(II) oxide is classified as a basic metal oxide. Several million kilograms are produced annually of varying quality, mainly as an intermediate in the production of nickel alloys. It is a green-black cubic crystal. It is soluble in acid and ammonia but insoluble in water. Is nickel oxide soluble? Nickel oxide is soluble in acids, potassium cyanide, and ammonium hydroxide. It is insoluble in both cold and hot water, and caustic solutions. The color turns yellow when heated. It is obtained by the action of nickel and oxygen at a temperature greater than 400°C, or by pyrolysis of nickel carbonate at 350°C. Used to make alloys, batteries, glass, enamel, ceramics, electronic components, nickel salts, and catalysts. 

Main properties of Nickel oxide 

 
What is the charge of NiO? 
0 is the charge of NiO.
Nickel oxide is the main oxide of nickel. It is classified as an alkali metal oxide. Millions of kilograms of products with different qualities are produced every year, mainly as intermediates for nickel alloy production. The mineral form of NiO (arsenite) is very rare. The protection of other nickel(III) oxides, such as Ni2O3 and NiO2 is also claimed but has not been proven by X-ray crystallography.

Conceptually simple structures are often called rock salt structures. Like many other binary metal oxides, NiO is usually not stoichiometric, which means that the Ni:O ratio deviates from 1:1. In nickel oxide, this non-stoichiometric NiO is accompanied by a color change. The stoichiometric correct NiO is green, and the non-stoichiometric NiO is black.

Performance of Nickel Oxide NiO Powder :
Nickel oxide is obtained by the action of nickel and oxygen at greater than 400℃, or by pyrolysis of nickel carbonate at 350℃. Used for making alloys, batteries, glass, enamel, ceramics, electronic components, nickel salts, and as a catalyst.

How is Nickel Oxide NiO produced?
NiO can be prepared by various methods. When heated to above 400°C, nickel powder reacts with oxygen to form NiO. In some commercial processes, green nickel oxide is made by heating a mixture of nickel powder and water at 1000°C. The reaction rate can be increased by adding NiO.
The simplest and most successful preparation method is to pyrolyze nickel (II) compounds (such as hydroxides, nitrates and carbonates) to produce a light green powder. By heating the metal in oxygen, the synthesis of the elements can produce gray to black powder, which indicates that the stoichiometry is wrong. It combines with sodium and potassium oxides at high temperatures (> 700°C) to form corresponding nickelates.
In addition, nickel oxide nanoparticles can be produced by thermally decomposing newly prepared nickel hydroxide through a sol-gel route at 300°C (572°F). X-ray diffractometer and vibrating sample magnetometer can be used to characterize the nickel oxide nanoparticles produced by this method.

Technical Parameter of Nickel Oxide NiO Powder :

Application of Nickel Oxide NiO Powder :
NiO has a variety of professional applications. Usually, it is used to distinguish between “chemical grade” and “metallurgical grade”. “Chemical grade” is a relatively pure material used for special applications, while “metallurgical grade” is mainly used to produce alloys. Used in the ceramic industry to manufacture glass powder, ferrite, and enamel. The sintered oxide is used to produce nickel steel alloys. Charles Edouard Guillaume (CharlesÉdouard Guillaume) won the 1920 Nobel Prize in Physics for his research on nickel-steel alloys, which he called Invar and Invar. 
What is nickel oxide used for?
Nickel oxide has a range of applications such as: For making electrical ceramics such as thermistors and varistors e.g. ferrites (nickel-zinc ferrite) Pigments for ceramic, glasses, and glazes.
NiO is a commonly used hole transport material in thin-film solar cells. It is also a component of nickel-iron batteries (also known as Edison batteries) and a component of fuel cells. It is the precursor of many nickel salts, used as specialty chemicals and catalysts. Recently, until the development of environmentally friendly NiMH batteries, NiO was used to manufacture NiCd rechargeable batteries used in many electronic devices.
Is nickel oxide toxic? 
CLINICAL FEATURES: ACUTE EXPOSURE Although nickel oxide is a pulmonary irritant, acute exposure is unlikely to result in significant poisoning. Documented clinical cases invariably involve chronic occupational inhalation.
NiO is an anode electrochromic material and has been extensively studied as a counter electrode of tungsten oxide and cathode electrochromic material in complementary electrochromic devices.
NiO is used as a binder and colorant for enamel in the pusher industry.
The ceramic industry is used as a raw material for colorants.
Used as a raw material for nickel-zinc ferrite in the production of magnetic materials.
Colorant for stained glass and tubular glass bulbs in the glass industry.
It is also a material used to manufacture nickel salts, nickel catalysts and secondary batteries.
Nickel oxide can react with acids to form salts and other compounds, such as nickel oxide. Nickel sulfamate for electroplating and nickel molybdate for hydrodesulfurization catalyst
Gold-doped nickel oxide films can be used as transparent electrodes in optoelectronic devices.
