Definition and Usage Areas Cobalt sulfate heptahydrate
Cobalt sulfate heptahydrate appears as red monoclinic crystals that liquefy around 100°C at 250°C and become anhydrous. It is soluble in water, slightly soluble in ethanol, and especially soluble in methanol. Salts are paramagnetic.
It is formed by the reaction of metallic cobalt, oxide, hydroxide or carbonate with aqueous sulfuric acid.
In many cases, cobalt is obtained from ores via sulfate.
Hydrated cobalt(II) sulfate is used in the preparation of pigments and in the manufacture of other cobalt salts. Cobalt pigment is used in porcelain and glass. Cobalt(II)sulfate is used in accumulators, electroplating baths, sympathetic inks, and as an additive to soils and animal feeds. For this purpose, cobalt sulfate is produced by treating cobalt oxide with sulfuric acid.
Cobalt(II) Sulfate Heptahydrate is a moderately water and acid soluble Cobalt source for uses compatible with sulfates. Sulfate compounds are salts or esters of sulfuric acid formed by replacing one or both of the hydrogens with a metal. Most metal sulfate compounds are readily soluble in water for uses such as water treatment, unlike fluorides and oxides which tend to be insoluble. Organometallic forms are soluble in organic solutions and sometimes in both aqueous and organic solutions. Metallic ions can also be dispersed utilizing suspended or coated nanoparticles and deposited utilizing sputtering targets and evaporation materials for uses such as solar cells and fuel cells. Cobalt Sulfate Heptahydrate is generally immediately available in most volumes. High purity, submicron and nanopowder forms may be considered. American Elements produces to many standard grades when applicable, including Mil Spec (military grade); ACS, Reagent and Technical Grade; Food, Agricultural and Pharmaceutical Grade; Optical Grade, USP and EP/BP (European Pharmacopoeia/British Pharmacopoeia) and follows applicable ASTM testing standards. Typical and custom packaging is available. Additional technical, research and safety (MSDS) information is available as is a Reference Calculator for converting relevant units of measurement.
