Cobalt compound:

Cobalt sulfate heptahydrate (CoSO4.7H20) is a common cobalt compound that appears as a blue crystallinesolid and is soluble in water. In the air, it will gradually lose the crystal water and become a powder. Cobaltsulfate heptahydrate is widely used in chemical experiments, It can be used as a catalyst in organic synthesisreactions. In addition, it can also be used to prepare other cobalt compounds, such as cobaltates and cobaltoxides, It can also be used for industrial applications such as electroplating, dyeing, and pigment preparation

Usage:

1. Cobalt sulfate is feed nutrition fortifier, Cobalt is a component of vitamin B12 that promotes red blood cellsynthesis and protein metabolism.

2. Electroplating industry for cobalt plating solution. It is also used as cobalt ferromagnetic materials, paintdhying agents, glaze for colored porcelain, additives for alkaline batteries, chemical analysis reagents andcatalysts.

Production method:

Cobalt metal is dissolved in a mixture of sulfuric acid and nitric acid (about 4:1). When the mass fractionreaches 22%%-23%, the steam is directly heated to boiling when the mass fraction reaches 43%-44%, thecrystallization can be carried out (3-4) days, and the fimished product is separated by centrifugation. The morethe mass fraction of the mother liquor is 30%, the more 35%-36% sulfuric acid solution is added. and then asmall amount of nitric acid is added to dissolve the metal cobalt. The NO3 (NO) produced in the reaction isquickly absorbed by air NO2, and ammonium nitrate is produced by ammonia.
