Nickel (II), an oxide of nickel, is a green-black, powder with the chemical Formula NiO. The Chemical Formula NiO is an intrinsic, p-type semiconductor, which has a large bandgap as well as good thermal and chemical stabilities.
The particle size is 6.
Nickel Oxide –
Nickel Oxide Is an inorganic compound with the chemical formula NiO and a mass of 74.71.
What does NiO mean in chemistry?
Nickel oxide, a chemical compound with formula NiO. It is also the principal nickel oxide. Nio Nickel Oxide is a basic metaloxide. A few million kilograms of it are made annually. This is used mainly to produce nickel alloys. It’s soluble in acids and ammonia, but insoluble when water.
Can nickel oxide be dissolved? Nickel dioxide is easily soluble in acids and potassium cyanide. It does not dissolve in cold or hot water. It turns yellow when heated. The color can be obtained from the reaction of nickel and oxygen at temperatures greater than 400°C. Or by pyrolysis nickel carbonate at 350°C.

What’s the Charge of NiO?
Charge of NiO: 0
Nickel oxide, the primary oxide of nickel is called it. It’s classified as an acidic metal oxide. Each year, millions of kilograms of various products are manufactured. They serve primarily as intermediates to the manufacture of nickel alloys. It is rare to find the NiO mineral (arsenite). Other nickel(III-oxides) such as Ni2O3 (or NiO2), are also protected. However, this hasn’t been proved by Xray crystallography.

NiO is a NaCl-based structure that includes O2-positions and octahedral Ni2+. Rock salt structures can be described as simple and conceptually straightforward structures. NiO is often not stoichiometric like other binary metaloxides. It means that the NiO:O ratio is less than 1:1. Nickel oxide has a non-stoichiometric, color changing NiO. The correct stoichiometric NiO color is green and the incorrect non-stoichiometric is black.
Performance of Nickel Oxide NiO Powder :
Nickel oxide is made from the combination of oxygen (at greater than 400) and nickel. Or, nickel carbonate can be pyrolyzed at 350. This metal is useful for the production of alloys.
How does Nickel Oxide NickelOiO be made?
You can prepare NiO using a variety of methods. Nickel powder forms NiO when it is heated to over 400°C. Some commercial processes use green nickel oxide by heating mixtures of nickel powder, water and heat at 1000°C.
To produce light green powder, the easiest preparation is to pyrolyze Nickel (II) compounds. If the metal is heated with oxygen, it can be resuspended in order to produce gray or black powder. The metal reacts with the sodium and potassium oxides at very high temperatures (> 700°C), to create the nickelates.
Additionally, nickel oxide nanoparticles are possible by thermally decomposing new prepared nickel hydroxide via a sol-gel method at 300°C (572°F). To characterize nickel oxide nanoparticles made by this process, an X-ray scatterometer and vibrating magnetometer are available.
Technical Parameters of Nickel Oxide NiO powder :
Nickel Oxide NiO Pulp :
NiO is used for a wide variety of professional purposes. It’s used to identify between “chemical” and “metallurgical”. The chemical grade, which is relatively pure and is only used for specific applications, is “metallurgical quality”, which is mostly used to create alloys. This is used to produce glass powder and ferrite in the ceramic industry. This sintered oxide is used for the manufacture of nickel steel alloys. Charles Edouard Guillaume (CharlesÉdouard Guillaume), was awarded the 1920 Nobel Prize in Physics in Physics for his research into nickel-steel alloys. This he named Invar or Invar.
How is nickel oxide used?
Nickel oxide is used in a wide range of industries, such as the manufacture and repair of varistors and thermostors. ferrites (nickelzinc-ferrite) Pigments to ceramic, glazes and glasses.
The most common hole transport material for thin-film solar cell is NiO. Also, it is a component in nickel-iron battery (also called Edison batteries), and also used as a fuel cell component. It is used to make specialty chemicals and catalysts. NiO, which was the precursor to many nickel salts, was widely used until the advent of NiMH rechargeable batteries.
Is nickel oxide toxic?
CLINICAL FEATURES. ACUTE EXPOSURE. Although nickel oxide can be a pulmonary irritating agent, it’s unlikely that acute exposure will cause significant poisoning. Inhalation from occupational work is a common factor in documented cases.
The anode electrodechromic NiO material has been thoroughly studied in order to be used as a counter-electrode of tungsten dioxide and cathode material for complementary electrochromic devices.
The pusher and enamel industries use NiO as a colorant and binder for enamel.
As a source of raw materials for colorants, the ceramic industry can be used.
This is used as a source of nickel-zinc ferrit in the manufacturing of magnetic materials.
For stained glass, colorant used in tubular and tube glass bulbs.
It can also be used for the production of nickel salts, catalysts, secondary batteries and other metals.
Nickel oxide can react to acids to make salts such as nickel molybdate for hydrodesulfurization catalyst. Nickel molybdate and nickel sulfamate are used for electroplating.
Transparent electrodes can be made from gold-doped Nickel Oxide films.
Storage condition of Nickel Oxide NiO Pulp :
Nickel Oxide NiO Pulp should be kept cool in a ventilated place. It should be kept away from heat and flames. You should keep it separate from any acids or edible chemicals. Mixing is not recommended. The storage space should have adequate materials to stop leakage.
Shipping and Packing of Nickel Oxide NiO powder :
You can pack it in two plastic bags with the inside.
Nickel Oxide NiO Powder Packaging: 100g, 500g, 1kg/bag or 25kg/barrel. Or as requested.
Nickel Oxide NiO Pulp shipping: could send out via sea, air or express once the payment has been received.
