Nickel(III) oxide: Property

What is Nickel(III) Oxide?

What is the name of ni2o3? Nickel(III) oxide, also known as nickelic oxide, is an inorganic compound with the chemical formula Ni₂O₃ and CAS number 1314-06-3. It has a molecular weight of 165.42 and is a gray-black powder with high chemical stability, being insoluble in water. It dissolves in sulfuric and nitric acids, releasing oxygen, and produces chlorine when dissolved in hot hydrochloric acid. It is used in the coloration of ceramics, glass, and enamel, and is also utilized in the production of nickel powder and in magnetic material research. As of October 27, 2017, nickel compounds are listed as Group 1 carcinogens by the International Agency for Research on Cancer (IARC).

What is the formula for Nickel iii Oxide?

The chemical formula of Nickel(III) oxide is Ni₂O₃. It may have a lattice structure and is considered a complex transition metal oxide. Theoretical calculations suggest it might adopt a distorted perovskite structure, with nickel ions (Ni³⁺) surrounded by oxygen ions (O^2-). However, due to the non-integer ratio of nickel to oxygen and potential structural distortions, determining the precise crystal structure of Nickel(III) oxide is challenging. Advanced characterization methods such as X-ray diffraction and electron microscopy are expected to reveal its true structural features, providing a basis for understanding its properties.

Is nickel III oxide soluble?

Nickel(III) oxide is insoluble in water, with negligible solubility in H₂O. It is slightly soluble in cold acids and dissolves in hot sulfuric or nitric acids with oxygen release, and in hot hydrochloric acid with chlorine release. Nickel(III) oxide is typically used in various applications due to its thermal stability and insolubility. Its insolubility is a key characteristic that adds value in applications such as:

• Glass, Optical, and Ceramic Applications: Its stability and insolubility help maintain its properties in these materials, ensuring durability and performance.
• Electronic Components: Its insolubility is useful for components requiring stability and corrosion resistance.
• Structural Components: In aerospace and other applications requiring lightweight materials, its insolubility ensures long-term structural integrity.
• Electrochemical Applications: In fuel cells, its insolubility contributes to improved stability and long-term performance of the cells.

Preparation

Jianhua Hu and colleagues reported a method for preparing analytical grade Nickel(III) oxide as follows:

1. Iron Removal from Nickel Nitrate: Dissolve 1 kg of nickel nitrate in 3000 mL of distilled water, add 10 g of hydrogen peroxide, heat to 80°C, and slowly add a 85 g/L sodium carbonate solution while stirring. Control the solution pH to 1.7, continue adding sodium carbonate until the pH reaches 4.0, filter to obtain Solution A.
2. Calcium and Magnesium Ion Removal: Heat Solution A to 85°C, slowly add ammonium fluoride, control the pH to 5.0, let it sit for 2 hours, then filter to obtain Solution B.
3. Synthesis of Nickel Oxalate: Concentrate Solution B at 50°C to a relative density of 15°Be, add 1.04 g/L oxalic acid solution while stirring, control the pH to 4.5 to form nickel oxalate precipitate. Wash the precipitate three times, dry, and obtain nickel oxalate.
4. Preparation of Analytical Grade Nickel(III) Oxide: Transfer the nickel oxalate to a nickel tray, calcine at 200°C for 3 hours, cool, grind, and sieve to obtain analytical grade Nickel(III) oxide.
