For professionals in chemical procurement and research and development, understanding the precise technical specifications of chemical compounds is fundamental to successful application and process optimization. This guide provides detailed technical information on Tungstic Acid (CAS 7783-03-1), highlighting its key parameters and their relevance for industrial users. As a dedicated manufacturer and supplier, we ensure our product meets rigorous standards.

Tungstic Acid: Chemical Identity and Basic Properties

Product Name: Tungstic Acid CAS Number: 7783-03-1 Chemical Formula: H2WO4 Molecular Weight: 249.85 g/mol

Tungstic Acid is an inorganic compound, typically appearing as a yellow powder. Its chemical behavior is characterized by its insolubility in water but solubility in alkaline solutions, which form tungstate salts. This property is leveraged in its processing and application.

Key Technical Specifications for Industrial Use

When procuring Tungstic Acid for industrial purposes, the following specifications are crucial:

• Appearance: Yellow powder. The consistent appearance is an initial indicator of product quality.
• WO3 Content: This is a primary measure of the tungsten content and purity. Our Tungstic Acid typically ranges from 88.0% to 91.0% WO3. This specification is critical for downstream conversion yields and product performance, particularly in tungsten powder and tungsten carbide manufacturing.
• Impurities: Low levels of metallic impurities are vital. For instance:
  • Al (Aluminum): 0.001% max
  • As (Arsenic): 0.005% max
  • Bi (Bismuth): 0.001% max
  • Ca (Calcium): 0.002% max
  • Co (Cobalt): 0.002% max
  • Cu (Copper): 0.001% max
  • Fe (Iron): 0.001% max
  • K+Na (Potassium+Sodium): 0.015% max
  These impurity limits ensure that the final tungsten products meet demanding performance criteria without undesirable side effects.
• Solubility Characteristics: While insoluble in water, its solubility in alkali solutions is key for its chemical processing into other tungsten compounds.

Packaging and Storage Recommendations

Our Tungstic Acid is packaged in 25kg cardboard drums, designed for safe handling and transport. Proper storage in a cool, dry, well-ventilated warehouse, away from heat and ignition sources, is recommended to maintain product integrity. Referencing the Material Safety Data Sheet (MSDS) is essential for detailed handling procedures.
