Sodium Tungstate Dihydrate (Na₂WO₄·2H₂O, CAS 10213-10-2) or Sodium Orthotungstate is the most used water-soluble tungsten salt, supplied by Scimplify at 99.63% purity for industrial and laboratory applications worldwide. Unlike APT, which is primarily a metallurgical intermediate, Sodium Tungstate is prized for its immediate solubility, making it the primary choice for aqueous-based chemical processes and flame-retardant treatments. Our Sodium Tungstate Dihydrate is a premium, high-solubility inorganic salt engineered for textile finishing, metal recovery, and specialized biochemical analysis. As a renowned Sodium Tungstate manufacturer and supplier, we ensure our material meets global regulatory standards, including REACH (EU) registration and RMI conflict-free mineral sourcing protocols. This material is essential for creating fire-resistant textiles and serves as a critical reagent in Folin-Ciocalteu clinical testing. Whether you are formulating corrosion inhibitors, producing phosphotungstic acid, or adjusting the density of heavy-media separation fluids, Scimplify delivers the chemical consistency, international SDS/MSDS/COA transparency, and reliable bulk logistics required for global technical excellence.

Chemical Properties & Specifications
Acute Tox. 4 (100%)
P264, P270, P301+P317, P330, and P501
Flameproofing agent for fabrics, particularly when mixed with ammonium phosphate. It also serves as a "weighting agent" in the silk industry, increasing the density and improving the "drape" of high-end fabrics
In laboratory environments, fundamental component of the Folin-Ciocalteu reagent, used to measure protein concentrations and phenolic content in biological samples. Catalyst in organic synthesis, specifically for the oxidation of secondary amines
High density of tungstate solutions, Used to prepare heavy liquids for mineralogical analysis (gravity separation). Allows geologists to separate minerals of different densities safely compared to traditional organic heavy liquids.
Highly stable. Efflorescent (loses water of crystallization) in dry air
Store in a cool, dry, well-ventilated area. Keep containers tightly closed. It is slightly hygroscopic; prevent moisture ingress to avoid caking
Non-hazardous for transport. Available in fiber drums, plastic-lined bags, or 1000kg "Big Bags" for international industrial distribution
The Dihydrate (10213-10-2) is the most stable and commonly used form. The Anhydrous (13472-45-2) form is rarely used unless your process is extremely moisture-sensitive. Most commercial "Sodium Tungstate" is the Dihydrate, containing approx. 70% Tungsten (W).
Yes. We offer an Analytical Reagent (AR) Grade with purity ≥ 99.5%. We strictly monitor for impurities like Molybdenum (Mo), Arsenic (As), and Chloride (Cl), which are critical for sensitive biochemical assays.
Yes. Tungstate ions act as an anodic corrosion inhibitor. They form a protective passivating film on steel and aluminum surfaces, particularly in "closed-loop" cooling systems where environmental friendliness is a priority over chromate-based inhibitors.
Absolutely. Like our APT, all Sodium Tungstate is sourced from Conflict-Free mines. We maintain full documentation through our supply chain to comply with the Dodd-Frank Act and EU Conflict Mineral regulations.
