Description
Nickel carbonate, also known as nickel(II) carbonate, is an inorganic compound with the chemical formula NiCO3. It is a greenish powder that is soluble in water and exhibits basic properties. Nickel carbonate is a versatile precursor for various nickel compounds and has applications in different industries.
Uses
Used in Electroplating Industry:
Nickel carbonate is used as a precursor to catalysts and an intermediate in the hydrometallurgical purification of nickel from its ores. It is also used as a neutralizing agent in nickel plating solutions, which helps to improve the quality and performance of the electroplated nickel coatings.
Used in Ceramic Industry:
Nickel carbonate is used in ceramic applications, where it serves as a colorant for producing various shades of green and yellow in ceramic glazes and pigments. Its ability to impart specific colors makes it a valuable component in the manufacturing of ceramic pigments.
Used in Catalyst Preparation:
Nickel carbonate is used to prepare nickel catalysts, which are essential in various chemical reactions and industrial processes. These catalysts play a crucial role in promoting and accelerating reactions, leading to increased efficiency and productivity.
Used in Metal Phosphating:
Nickel carbonate is utilized in metal phosphating processes, where it helps to form a protective phosphate coating on metal surfaces. This coating provides enhanced corrosion resistance and improves the adhesion of subsequent coatings, such as paints or powder coatings.
Used in Glass Coloring:
Nickel carbonate is used for coloring glass, where it imparts a greenish hue to the glass material. This property makes it a valuable component in the production of colored glass products, such as bottles, windows, and decorative items.
Preparation
Anhydrous nickel carbonate is produced as a precipitate when calcium carbonate is heated with a solution of nickel chloride in a sealed tube at 150°C. Alternatively, treating nickel powder with ammonia and carbon dioxide followed by boiling off ammonia yields pure carbonate.
When sodium carbonate is added to a solution of Ni(II) salts, basic nickel carbonate precipitates out in impure form.
Reactions
Nickel carbonate is the starting material for preparing many nickel salts. It reacts with dilute acids evolving carbon dioxide, and upon evaporation of the solution corresponding nickel salts are formed. The nitrate, sulfate and phosphate salts are prepared from carbonate. Similarly, reactions with hydrofluoric, hydrochloric, hydrobromic, or hydriodic acids yield hydrated nickel halides: namely NiF2?4H2O, NiCl2?6H2O, NiBr2?6H2O, and NiI2?6H2O, respectively:
NiCO3 + HCl → NiCl2?6H2O + CO2
NICKEL CARBONATE 611Nickel carbonate decomposes to nickel oxide when strongly ignited:
NiCO3 → NiO + CO2
Nickel carbonate, when dissolved in aqueous thiocyanic acid, yields a yellow brown precipitate of hydrated nickel thiocyanate:
2 NiCO3 + 2HSCN → Ni(SCN)2 + CO2 + H2O
Nickel carbonate forms many double salts, such as, Na2CO3?NiCO3?10H2O with alkali metal carbonates. However, such double carbonates usually are prepared by mixing an alkali metal or ammonium bicarbonate solution with a nickel salt solution, followed by crystallization.
Hazard
Confirmed carcinogen.
Safety Profile
Confirmed human
carcinogen. When heated to decomposition
it emits toxic vapors of nickel.
Check Digit Verification of cas no
The CAS Registry Mumber 3333-67-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,3,3 and 3 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 3333-67:
(6*3)+(5*3)+(4*3)+(3*3)+(2*6)+(1*7)=73
73 % 10 = 3
So 3333-67-3 is a valid CAS Registry Number.
