The role of nickel oxide in glaze

 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, soluble in acid and ammonia, insoluble in water, and changes color to yellow when heated. It is obtained by the action of nickel and oxygen at temperatures above 400 °C, or by the pyrolysis of nickel carbonate at 350 °C. For the manufacture of alloys, batteries, glass, enamel, ceramics, electronic components, nickel salts, and as a catalyst.

Nickel oxide NiO powder 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 in the production of nickel alloys. The mineral form of NiO (arsenite) is very rare. Other nickel(III) oxides are also claimed, such as Ni2O3 and NiO2, but have not been confirmed by X-ray crystallography.

The nickel oxide NiO powder adopts the NaCl structure with octahedral Ni2+O2 sites. Conceptually, simple structures are often referred to as rock-salt structures. Like many other binary metal oxides, NiO is generally 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. Stoichiometrically correct NiO is green and non-stoichiometric NiO is black.

Nickel oxide NiO powder is obtained by the action of nickel and oxygen at temperatures above 400 °C, or by pyrolysis of nickel carbonate at 350 °C. Used in the manufacture of alloys, batteries, glass, enamels, ceramics, electronic components, nickel salts and as catalysts. Nickel oxide NiO can be prepared by various methods. When heated above 400°C, the nickel powder reacts with oxygen to form NiO. In some commercial processes, green nickel oxide is mixed by heating nickel powder and water at 1000°C. The addition of NiO can increase the reaction rate.

The simplest and most successful preparation method is the pyrolysis of nickel(II) compounds such as hydroxides, nitrates and carbonates to produce a pale green powder. By heating the metal in oxygen, elemental synthesis produces gray to black powders, indicating that the stoichiometry is wrong. It combines with sodium and potassium oxides to form the corresponding nickelates at high temperatures (>700 °C).

Furthermore, nickel oxide nanoparticles can be prepared by thermal decomposition of freshly prepared nickel hydroxide at 300 °C (572 °F) via a sol-gel route. X-ray diffractometer and vibrating sample magnetometer can be used to characterize the prepared nickel oxide nanoparticles by this method.

Application of Nickel Oxide NiO Powder

Nickel oxide NiO has a variety of professional uses. Often 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. It is used in the ceramic industry to manufacture glass powder, ferrite and enamel. Sintered oxides are used to produce nickel steel alloys. Charles Edouard Guillaume won the 1920 Nobel Prize in Physics for his work on nickel-steel alloys, which he called Invar and Invar.

Nickel oxide NiO is a commonly used hole transport material in thin film solar cells, and is also a component of nickel-iron batteries (also known as Edison cells) and fuel cells. It is the precursor of many nickel salts and is commonly used as specialty chemicals and catalysts . More recently, until environmentally friendly NiMH batteries were developed, NiO was used to make NiCd rechargeable batteries used in many electronic devices. Electrochromic devices.

Nickel oxide NiO is used in the push rod industry as a binder and colorant for enamels.

The ceramic industry is used as a raw material for colorants.

It is used as a raw material for nickel-zinc ferrite in the production of magnetic materials.

Colorants for stained glass and tubular glass bulbs in the glass industry.

It is also a material used in the manufacture of nickel salts, nickel catalysts and secondary batteries.

Nickel Oxide NiO can react with acids to form salts and other compounds such as nickel oxide. Nickel sulfamate and electroplating hydrodesulfurization catalyst

Nickel oxide films doped with gold with nickel molybdate can be used as transparent electrodes in photovoltaic devices.
