Description

The minimum scope of supply from 25 kg, bag

Sulfate of cobalt represents crystal substance from pink till red color, salt of bivalent cobalt and sulphuric acid. It is very hygroscopic. Well (but slowly) it is dissolved in water. It is badly dissolved in ethanol, concentrated sulphuric acid, it is slightly better - in methanol and glycerin. It is recovered by sulfur, carbon, metal cobalt.

Anhydrous sulfate of cobalt (II) exists in two crystal modifications: α-CoSO4 pink color, has rhombic singoniya of crystal lattice and β-CoSO4 lilac color, has monoklinny singoniya of crystal lattice.


Sulfate of cobalt meets in the nature in the form of minerals of aplouit, moorhouseite and bieberite.

At sedimentation and at moisture absorption sulfate of cobalt (II) forms number of crystalline hydrates of solutions:
- CoSO4 heptahydrate7H2O - red crystals with monoklinny singoniya. Also two metastable modifications of heptahydrate - from rhombic and monoklinny singoniyama are known.
- hexahydrate of CoSO46H2O - orange-red crystals with monoklinny singoniya.
- monohydrate of CoSO4H2O - pink crystals with monoklinny singoniya.
Besides, metastable hydrates with 4 and 2 water molecules are known.
The most widespread type of sulfate of cobalt is heptahydrate of sulfate of cobalt.

Density: anhydrous 3,71 g/cm ³, monohydrate: 3,075 g/cm ³; hexahydrate: 2,029 g/cm ³; heptahydrate - 1,948 g/cm ³. Temperature of decomposition is 600-700 °C.

Chemical formula: CoSO4.

In the electrochemical industry, it is used as sushitel of lithographic ink, varnishes, paints and linoleum.
Besides, it can be used as the catalyst, analytical reactant, tire glue, etc.
Cobalt is considered irreplaceable element for live organisms, including people as it enters B12 vitamin molecule.

Cobalt sulfate safety requirement.
Sulfate of cobalt is moderate toxic substance. Can cause violations of digestion, breath, blood system, and also sharp dermatitis. At contact with skin can cause allergic reaction. At hit in organism can render mutagen effect, influence reproductive function.
The main symptoms of poisoning with sulfate of cobalt include diarrhea, appetite loss, temperature drop of body and arterial pressure.
Sulfate of cobalt (II) is capable to cause long-term adverse changes in aqueous medium.
The fire - it is also explosion-proof.

Packaging, transportation and storage.
