Ammonium Paratungstate (APT) ((NH₄)₁₀[H₂W₁₂O₄₂]·xH₂O) (CAS 11120-25-5) is a critical tungsten intermediate widely supplied by ammonium paratungstate manufacturers and suppliers in the USA, serving as the benchmark compound for producing tungsten oxide (WO₃), tungsten metal powder, and downstream tungsten carbide. Supplied as a high-purity white crystalline material, APT is engineered for consistent solubility, controlled particle morphology, and reliable thermal decomposition behavior, making it the preferred feedstock for tungsten processors and advanced material manufacturers. In industrial practice, APT is produced through hydrometallurgical refining of tungsten concentrates, followed by controlled crystallization to ensure impurity control and batch consistency required by U.S. manufacturing standards. It is subsequently calcined to tungsten oxide and reduced to tungsten metal powder, which is widely used by tooling manufacturers, CNC machining suppliers, and component producers serving automotive and industrial equipment sectors. We are one of the trusted Ammonium Paratungstate manufacturers in the USA, offering 99% purity. Our product adheres to US standards with reliable sourcing, scalable volumes, and supply chain consistency aligned with domestic procurement and industrial requirements.

Ammonium Paratungstate is the primary upstream intermediate used by tungsten processors to produce tungsten oxide and subsequently tungsten metal powder, which is critical for cutting tools, aerospace components, and defense manufacturing supply chains.
Tungsten derived from APT is used in electronic components such as electrodes, filaments, and high-temperature electrical systems, supporting semiconductor manufacturing and advanced electronics production in the United States.
Ammonium paratungstate is used as a precursor for tungsten-based catalysts applied in petrochemical refining, hydrogenation, and environmental processing systems where stable catalytic performance is essential.
APT is used in ceramic formulations and pigment systems, including porcelain coloring and specialty materials, where tungsten compounds provide thermal stability and functional performance in high-temperature environments.
Stable at room temperature. When heated above 250°C, it begins to decompose, releasing ammonia and water to form tungsten trioxide (WO3)
Store in a cool, dry, well-ventilated warehouse. Keep containers tightly closed to prevent moisture absorption (hygroscopicity) which can cause caking.
Generally non-hazardous for transport. Available in 25kg/50kg plastic-lined woven bags, fiber drums, or 1000kg "Big Bags" for international industrial supply
The W03 content is the primary measure of value. Standard APT typically contains 88.5% to 89% W O3. A lower percentage usually indicates higher moisture or impurity levels, which can negatively affect the yield and grain size of the resulting tungsten powder.
Scimplify adheres to the Responsible Minerals Initiative (RMI) guidelines. We only source tungsten ore and concentrates from audited, conflict-free smelters and mines, providing full traceability documentation for your ESG compliance requirements.
Yes. The morphology and particle size of the APT crystals can influence the "Blue Tungsten Oxide" formed during calcination, which in turn affects the particle size of the final metal powder. We offer controlled crystal size grades to help you optimize your reduction process.
Yes, it is naturally a hydrate. While it contains water of crystallization, it remains a dry, free-flowing powder. This moisture is chemically bound and does not pose a leakage risk, allowing for standard international shipping in moisture-barrier packaging.
