Overview of nickel oxide NiO powder:
Nickel oxide is an inorganic substance with a chemical formula of NiO and a molecular weight of 74.71.It is a green-black cubic crystal.It is soluble in acid and ammonia,but insoluble in water.The color changes to yellow when heated.It is obtained by the action of nickel and oxygen at a temperature higher than 400°C,or by pyrolysis of nickel carbonate at 350°C.Used in the manufacture of alloys,batteries,glass,enamel,ceramics,electronic components,nickel salts,and as a catalyst.
Nickel oxide is the main oxide of nickel.It is classified as an alkali metal oxide.Millions of kilograms of different quality products are produced every year,mainly as intermediates for nickel alloy production.The mineral form of NiO (arsenite) is very rare.Other nickel (III) oxides are also claimed,such as Ni 2 O 3 and NiO 2,but they have not been proven by X-ray crystallography.
NiO adopts a NaCl structure with octahedral Ni2 + and O2 positions.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.NiO with correct stoichiometry is green,and NiO with non-stoichiometry is black.To
Nickel oxide is obtained by the action of nickel and oxygen at a temperature higher than 400°C,or by pyrolysis of nickel carbonate at 350°C.Used in the manufacture of alloys,batteries,glass,enamel,ceramics,electronic components,nickel salts,and as a catalyst.Nickel oxide NiO can be prepared by various methods.When heated 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 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.
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.
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.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 make 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 and hydrodesulfurization catalyst for electroplating
A nickel oxide film doped with gold with nickel molybdate can be used as a transparent electrode in a photovoltaic device.
