Sodium Tungstate Supplier in Malaysia
- Also known as
- Sodium Wolframate
- Disodium Tungstate
- Na2WO4
Sodium tungstate supplier enquiries in Malaysia cover sodium wolframate, Na2WO4, a soluble sodium salt used as a tungsten source. Buyers request it for hydrometallurgy, tungsten compound manufacture, catalyst preparation, ceramic materials and laboratory synthesis.
Sodium tungstate dihydrate is the common crystalline form, while anhydrous sodium tungstate is selected when water of crystallisation cannot enter the process. Technical and reagent grades are differentiated by tungsten basis, impurity limits and the process specification rather than by a generic product label.
Mining and chemical manufacturers use sodium tungstate as an intermediate for other tungsten compounds. Materials, electronic and research users may require a defined hydrate, solution behaviour or trace-metal profile, so the intended route should be named at quotation stage.
Send the hydration state, grade, specification, quantity and delivery location with your enquiry. Availability, packing, documentation, route and timing are confirmed with the quotation, and supply is subject to applicable requirements.
- Formula
- Na2WO4
- Grade

Sodium Tungstate 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 |
|---|---|---|---|---|
| Sodium tungstate dihydrate | white to colourless crystals or crystalline powder | — | Tungsten compound manufacture, hydrometallurgical processing and catalyst preparation where the dihydrate is the specified soluble tungstate. | Packing format is confirmed with the quotation. |
| Anhydrous sodium tungstate | white crystalline powder | — | Materials, ceramic and synthesis routes where water of crystallisation cannot be carried into the charge and anhydrous Na2WO4 is specified. | Packing format is confirmed with the quotation. |
| Technical sodium tungstate | crystals or powder, as specified | — | General industrial tungsten chemistry and process work where tungsten basis, hydration state and impurity limits are set by the buyer. | Packing format is confirmed with the quotation. |
| Reagent grade sodium tungstate | crystalline powder | — | Analytical, laboratory and research synthesis requiring a defined tungstate salt with tighter impurity control than a general technical grade. | Packing format is confirmed with the quotation. |

Common questions about sodium tungstate
Which form of sodium tungstate is commonly requested?
Sodium tungstate dihydrate is a common crystalline form, while anhydrous sodium tungstate is chosen when water of crystallisation cannot enter the process. State the hydration state and tungsten basis with the enquiry because the two forms should not be compared weight for weight without a specification.
Is sodium tungstate the same as tungsten trioxide?
No. They are different tungsten products. Sodium tungstate is a soluble sodium salt used as a process or synthesis input, while tungsten trioxide is an oxide with its own composition and applications. Request the compound named by the process rather than substituting one for the other.
What is sodium tungstate used for?
It is used as a soluble tungsten source in hydrometallurgy, tungsten compound manufacture, catalyst preparation, ceramic and advanced-material routes, and laboratory synthesis. The required hydrate and impurity profile depend on the process, so include the application in the enquiry.
What specifications should a buyer provide?
Give the hydration state, grade, tungsten basis, purity or impurity limits, physical form, quantity and delivery location. Add the process route and any particle-size or solution-preparation requirement that controls the material selection.
How should sodium tungstate be stored?
Keep the crystals or powder sealed in a dry store and protect them from contamination or unintended moisture exchange. Follow the safety information issued with the quoted grade and the buyer's own workplace procedure.
How is sodium tungstate priced for industrial enquiries?
The quotation depends on hydration state, grade, tungsten basis, impurity limits, quantity and delivery location. Send the complete requirement so the offer can be issued with a stated validity period and confirmed commercial terms.
