Nickel oxide overview
Compounds with the chemical name NiO are compounds containing nickel (II). It is the principal oxide of Nickel. Nickel oxide, a thermally stable, highly insoluble source of nickel, is suitable for applications such as glass, ceramics, and optics. Nickel oxide, the main nickel oxide, is a green solid. Every year, millions of kilos of nickel oxide powder (NiO), which is 99.999% pure in nature are produced. Oxide doesn't conduct electricity.
Nevertheless, certain oxides containing a perovskite structural structure are conductible in the cathodes for solid oxide fuel cell and oxygen production systems. Compounds containing one or more metal cations and at least one oxygen ion. These compounds are stable and insoluble in aqueous solution (water). They can be used for ceramic structures and even for the production of simple clay bowls to house advanced electronic devices.
Metal oxides react with acids, strong reducing substances and oxidizing agents. Nickel oxide can be produced as powders, tablets, sputtering nozzles, or small pieces. In many cases, nickel dioxide is readily available. Nickel oxide in high purity, nanopowder and submicron forms are possible.
What uses does nickel oxide have?
Nickel oxide can be used for electrical ceramics like thermistors or varistors. As a ceramic, glass and glaze pigment, ferrite (nickelzinc ferrite), can be used.
NiO can be used for a number of professional purposes. In general, "chemical grade" is distinguished from "metallurgical quality". Chemical grade is a relatively purified material that is used in special applications. "Metallurgical grade", on the other hand, is mainly used to create alloys. It is used by the ceramic industry for glass frit, enamel and ferrite. It is used in the production of nickel steel alloys. Charles Edouard Guillaume received the 1920 Nobel Prize in Physics in recognition of his research on nickel steel alloys he named Invar and Irenevar.
NiO, or hole transport material, is used in thin-film photovoltaic cells. NiO is also used in the manufacture of nickel-iron battery (also called Edison batteries) as well as fuel cells. It is also the precursor of several nickel salts used in specialty chemicals and as catalysts. NiO has been used to make NiCd rechargeable battery used in electronic devices until recently. In complementary electrochromic devices, NiO is used as anode electrode instead of tungsten dioxide (cathode electrode).
About 4,000 tons of chemical-grade NiO are produced annually. Black NiO, formed from mineral acid treatment, is the precursor to nickel sal. NiO can be used as a hydrogenation catalyst.
The reduction of nickel oxide to metallic Nickel can be achieved by heating with hydrogen or carbon. When heated to high temperatures (>700degC), nickel oxide can be combined with sodium and potassium oxides to produce corresponding nickelates.
Is nickel oxide soluble in water?
Nickel oxide dissolves in ammonium hydroxide, potassium cyanide, and acid. It is insoluble with hot and cold water as well as a caustic solution.
Use collinear nickel-oxide insulators in conjunction to generate spin-polarized voltage
The antiferromagnetic material has shown great promise in spintronics because it is resistant to magnetic field disturbances. It also does not produce stray fields and exhibits ultra-fast dynamic. It is still very difficult to create and manipulate spin-polarized ions in these materials due to their symmetry. The use of Nickel Oxide may help overcome the limitation.
We have constructed a prototype junction consisting of a gold-nickel-gold-gold junction, in which a collinear nickel oxide insulator can destroy the spin sublattice symmetry using an external bias voltage. A system like this demonstrates spin-polarized polarized currents when it induces non-equivalent transmittal of spin up and spin down currents.
Zhang Xianmin said, "Due the symmetry of spin sublattice it was long believed that spin polarized current could not be achieved in collinear materials." "Here, the bias voltage is used to break the symmetry of antiferromagnetic antiferromagnetic materials' spin sublattice, and a spin polarized current can then be induced."
This work provides an improvement to the large resistance mismatch which prevents the small spin injection into the semiconductor from the metal electrode. This will make it easier for spintronics to be combined with semiconductor electronic.
By changing the bias voltage, the team could not only adjust the amplitude but also the direction of spin polarization. The system can achieve 80% positive spin-polarization by using a bias voltage around 0.9 Volts. However, negative spin-polarization requires a voltage above 1.6 Volts.
Zhang hopes that his findings will pave a way for new antiferromagnetic spinning devices and hopes to explore further the manipulation of these materials.
Nickel oxide - acid or alkaline
Unless stated otherwise, the data provided on materials is at standard conditions. (At 25degC [77degF],100kPa). Nickel hydroxide, also known as NiO(OH), is a compound that has an inorganic formula. It is an insoluble black solid that will not dissolve in any solvent. However, it can be attacked with alkalis or acids.
Is nickel oxide magnetic?
Solution-growth method is used to produce branched nanocrystals of nickel oxide with a narrow size distribution. The magnetic characterization results show that NiO Nanocrystals less than 12.8 nm in size exhibit a weak ferromagnetic phase at room temperatures due to spins which are not compensated.
