Cobalt sulfate anhydrous is a sulfate salt of either divalent or trivalent cobalt. Divalent anhydrous cobalt sulphate melts at 96.8 C; soluble in methanol. Cobalt sulfate anhydrous is used in preparing pigments and other cobalt salts. Trivalent cobalt sulfate [called cobaltic sulfate, Co2(SO4)3] contains trivalent cobalt acts as an oxidizing agent; soluble in sulfuric acid. Cobalt pigment is used in porcelains and glass. Cobalt sulfate is used in storage batteries and electroplating baths. Cobalt sulphate anhydrous is used in sympathetic inks and as an additive to soils and animal feeds.


Stored in cool and dry warehouse; Keep away from flame and heat.

Packaging Sizes

25kg net. Double plastic bags lined plastic woven sack. Or reagent bottle packaging.


What is Cobalt Sulfate Anhydrous?

Anhydrous cobalt sulfate generally refers to cobalt (II) sulfate, which is an inorganic compound with the chemical formula CoSO4. It is a rose red crystalline powder and often exists in the form of various hydrates. Mainly used in ceramic glazes and paint drier, also used in electroplating, alkaline batteries, production of cobalt-containing pigments and other cobalt products. And it can also be used as catalysts, analytical reagents, feed additives, tire adhesives, lithopone additives, and so on.

Fire-fighting measures?

It cannot burn by itself. This product can release toxic gas when it is decomposed by high heat. Hazardous combustion products are sulfur oxides.

When extinguishing the fire, firefighters must wear full-body fireproof and anti-virus clothing, and put out the fire in the upwind direction and move the container from the fire scene to an open place as much as possible. Then select the appropriate fire extinguishing agent to extinguish the fire according to the cause of the fire.

Spill emergency treatment?

Isolate the leaked contaminated area and restrict access. Emergency personnel need to wear dust masks and protective clothing. Do not come into direct contact with spilled material.

Small amount of leakage: Avoid raising dust and sweep up carefully, collect and transport to waste disposal site for disposal.

Large amount of leakage: Collect and recycle or transport to waste disposal site for disposal.

Handling and storage?

Operation precautions: Airtight operation, local exhaust. Prevent dust from being released into the workshop air. Operators must undergo special training and strictly abide by the operating procedures. It is recommended that operators wear self-priming filter dust masks, chemical safety protective glasses, rubber acid and alkali resistant clothing and gloves. Avoid generating dust. Equipped with leakage emergency treatment equipment is necessary. Empty containers may contain hazardous residues.

Precautions for storage: Store in a cool, ventilated warehouse. Keep away from fire and heat sources. Keep out of direct sunlight. The packaging must be sealed and kept away from moisture. It should be stored separately from food chemicals, etc., and should not be stored together. Storage areas should be equipped with suitable materials to contain spills.
