Cobalt hydroxide is a hot research area in nanotechnology and materials science

Overview of Cobalt Hydroxide

Cobalt hydroxide is an inorganic substance with the chemical formula Co(OH)2. It is a rose-red monocline or hexagonal crystal system, insoluble in water, slightly amphoteric, difficult to dissolve in strong alkali, but soluble in acid and ammonium salt solution. The density is about 3.6g/cm³. Melting point 1100-1200℃, for amphoteric hydroxide. It is mainly used as a coloring agent for glass and porcelain enamels, raw material for making other cobalt compounds, and desiccant for varnishes and coatings.

Cobalt hydroxide is an inorganic compound consisting of the hydroxide ion Ho − from the cobalt divalent cation CO2 +. Pure compounds, often referred to as "β-type" (β-Co(OH)) are an insoluble pink solid, and the term also applies to related compounds, often referred to as the "alpha" or "blue" form (α-Co(OH))2), which contain other anions in their molecular structure. This compound is blue and very unstable cobalt hydroxide (II) is mainly used as a desiccant for paints, varnishes and inks, in the preparation of other cobalt compounds, as a catalyst and in the manufacture of battery electrodes.

Cobalt hydroxide (II) precipitates as a solid when the alkali metal hydroxide is added to an aqueous solution of CO2 + salt.

The compound can be composed of cobalt nitrate (II) in water with triethylamine N(C2 H5)3 as both an alkali and a complexing agent.It can also be prepared by electrolysis of cobalt nitrate solution with the platinum cathode.

Exposure to cobalt compounds may be sensitized by inhalation and skin contact. Dust generated during handling can cause irritation of the nose and throat. Prolonged exposure can cause serious respiratory disease and lung damage. Sensitive people may experience wheezing and shortness of breath.

Applications of Cobalt Hydroxide

Pure (β) cobalt hydroxide (II) has a brucite crystal structure. Thus, the accumulation of negative ions and cations is similar to cadmium iodide, where cobalt (II) cations with octahedral molecular geometry can be obtained in the form of beta platelets with partial hexagonal geometry, 100-300 nm wide and 5-10 nm thick.

Alpha form

The so-called "alpha form" (α-Co(OH)2) is not a pure (β) form of pleomorphism, but a more complex compound in which the hydroxide-cobalt-hydroxide layer has a residual positive charge and alternates with other anionic layers, such as nitrate, carbonate, chloride, etc. (hydrotalcite structure). When a base such as sodium hydroxide is added to a cobalt (II) salt solution, a blue precipitate is usually obtained. The precipitate slowly changes into beta form.

nanotubes

Cobalt hydroxide, which exists in the form of nanotubes, is a hot spot in nanotechnology and materials science.

In chemical production, it is used to manufacture cobalt salt, cobalt-containing catalyst and hydrogen peroxide decomposition agent by electrolysis.

Used as a paint drier in the coating industry.

Glass enamel industry used as a coloring agent, etc.
