Sodium Tungstate Dihydrate (CAS 10213-10-2), also known as Sodium Orthotungstate, is the most commercially used water-soluble tungsten compound across industrial and specialty chemical manufacturing in the United States. As a highly functional inorganic salt, it is widely used in corrosion inhibitor formulations, catalyst production, metal surface treatment, textile finishing, and analytical laboratory applications. Its excellent solubility and chemical stability make it the preferred tungsten source for aqueous processing and downstream tungsten compound synthesis. Scimplify is a trusted sodium tungstate manufacturer and supplier in the USA with high-purity (99.63%), industrial-grade material engineered for consistent performance and process reliability. Our sodium tungstate dihydrate supports critical applications including specialty chemical manufacturing, heavy-media separation, and advanced material production. Manufactured under strict quality control protocols, our material is supported by complete Safety Data Sheets (SDS) and Certificates of Analysis (COA) to meet U.S. regulatory and procurement standards. With dependable global supply capabilities, batch-to-batch consistency, and reliable lead times, we can offer competitive pricing (USD).

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.
