Cobalt Sulphate Supplier in Malaysia
- Also known as
- Cobalt Sulfate
- cobalt(II) Sulphate
- cobalt(II) Sulfate
- Cobaltous Sulphate
Cobalt sulphate supplier for electroplating, cathode precursor, catalyst and micronutrient buyers in Malaysia. The same salt is written cobalt sulfate, cobalt(II) sulphate, cobaltous sulphate and CoSO4, and it reaches the market as red to pink crystals or pink crystalline powder. Most trade is in the heptahydrate, with the monohydrate quoted where less water of crystallisation is wanted.
Grade language here follows the end use rather than one purity number. Plating grades are matched to bath chemistry, battery grades to cathode precursor impurity profiles, and technical grades to cobalt chemical, drier and ceramic colour work. Cobalt content is the trade parameter, so name the hydrate and the cobalt basis your specification uses.
Cobalt sulphate is not nickel sulphate or manganese sulphate, and the three are ordered as separate lines even when one bath or blend draws on more than one. Platers and precursor producers buy on assay and impurity limits, while agricultural and premix buyers take the salt as a trace cobalt input. Naming the application lets the hydrate, form and grade be matched properly.
Send the hydrate, grade, cobalt content basis, impurity limits, quantity and delivery location with your enquiry. Pack format, availability, documentation and delivery timing are confirmed with the quotation. Ask for the safety information covering the grade quoted, since cobalt salts need routine dust and skin precautions, and supply is subject to applicable requirements.

Cobalt Sulphate grades and forms
We supply several forms to suit different formulating and dosing setups. If you need a size that is not listed, ask us.
| Grade | Form | Assay | Typical use | Packing |
|---|---|---|---|---|
| Cobalt sulphate heptahydrate, plating grade | red to pink crystals | cobalt content as stated for the grade | Soluble cobalt addition to cobalt and cobalt-alloy electroplating baths and to surface-finishing chemistry, where bath assay and impurity limits govern the choice. | Pack format is confirmed with the quotation. |
| Battery grade cobalt sulphate heptahydrate | reddish-pink crystals or crystalline powder | cobalt content and impurity profile as stated for the grade | Cobalt feed for cathode precursor and energy-storage chemical routes that call for a tighter impurity profile than general industrial material. | Pack format is confirmed with the quotation. |
| Cobalt sulphate monohydrate | pink crystalline powder | cobalt content as stated for the grade | Requirements that prefer less water of crystallisation per unit of cobalt, including dry blending and shipments where freight per unit of cobalt is the deciding factor. | Pack format is confirmed with the quotation. |
| Technical grade cobalt sulphate | crystals or crystalline powder | — | Cobalt chemical manufacture, catalyst and metal-drier preparation, and ceramic, glass or pigment colour work where a technical grade meets the written specification. | Pack format is confirmed with the quotation. |
| Micronutrient grade cobalt sulphate | crystalline powder or fine crystals | — | Trace cobalt input for micronutrient blends, fertigation programmes and mineral premixes, against the quality requirements the buyer states. | Pack format is confirmed with the quotation. |

Specifications
| Parameter | Value | Method |
|---|---|---|
| Appearance | red to pink crystals or pink crystalline powder according to hydrate and grade | — |
| Commercial hydrates | heptahydrate is the usual traded form; monohydrate is quoted as its own material rather than as a substitute weight for weight | — |
| Molecular formula | CoSO4 for the anhydrous salt; CoSO4·7H2O for the heptahydrate | — |
| CAS number (heptahydrate) | 10026-24-1 | — |
| CAS number (anhydrous) | 10124-43-3 | — |
| Solubility | soluble in water | — |
| Assay basis | cobalt content, typical and grade dependent; the heptahydrate carries more water of crystallisation than the monohydrate, so the two differ on a cobalt basis | — |
| Usual impurity checks | nickel, iron, copper, zinc, chloride and insoluble matter, to the limits set by the plating, precursor or process specification | — |
Cobalt Sulphate applications
Safety and handling
Keep sealed in a cool, dry place away from moisture and incompatible materials. Cobalt salts need ordinary dust, skin and eye precautions, so control dust when weighing and use gloves and eye protection. Work to the safety information covering the grade quoted. Supply is subject to applicable requirements.
Common questions about cobalt sulphate
Is cobalt sulphate the same as cobalt sulfate?
Yes, the same material. Cobalt sulphate is the British spelling and cobalt sulfate the American one, and cobalt(II) sulphate, cobaltous sulphate and CoSO4 all describe it as well. One page covers every spelling, so state the hydrate and grade instead of the spelling.
Should I order cobalt sulphate heptahydrate or monohydrate?
The heptahydrate is the form most specifications name and most plating and precursor work uses. The monohydrate holds less water of crystallisation, so it carries more cobalt per kilogram and suits dry blending and freight-sensitive shipments. Do not swap them weight for weight without recalculating on a cobalt basis.
Is cobalt sulphate the same as nickel sulphate or manganese sulphate?
No. These are three separate metal sulphates with different process behaviour, and a bath or blend using more than one still needs each ordered by name. Send a line for each salt with its own grade and quantity.
How is cobalt sulphate assay stated?
Commercially it is stated as cobalt content rather than as a single purity figure, because the value depends on the hydrate and the grade. Give the cobalt basis your specification works to, together with any nickel, iron, copper, zinc or chloride limits, and the offer can be matched to it.
Which cobalt sulphate grade suits an electroplating bath?
Plating grade heptahydrate crystals are the usual choice for cobalt and cobalt-alloy baths, since bath chemistry is sensitive to trace metals a general technical grade may not control. Send the bath specification with the impurity limits it holds.
What is battery grade cobalt sulphate?
It is heptahydrate material selected for cathode precursor and related energy-storage manufacture, where the impurity profile is held tighter than on industrial grades. State the cobalt basis, the impurity limits and the form so the requirement is priced against the correct grade.
What should a cobalt sulphate price enquiry include?
Give the hydrate, grade, cobalt content basis, target impurity limits, quantity and delivery location, plus any pack size preference and documentation you need. Prices are issued with a stated validity period because cobalt moves with the metal market.
