Description

Sodium Nitrate CAS NO 15621-57-5 is an inorganic salt widely recognized for its role as a powerful oxidizing agent and a source of nitrate ions. This compound is critical in industrial processes where controlled oxidation or nitrogen fixation is required. Key industries that rely on this material include agriculture for fertilizer production, chemical manufacturing for synthesizing other nitrate compounds, and metallurgy for metal treatment and refining.

Application

• As a key nitrogen fertilizer component and soil nutrient supplement in agriculture.
• As an oxidizing agent in the production of explosives, pyrotechnics, and solid rocket propellants.
• In the glass and ceramics industry to modify melting properties and act as a fining agent.
• As a corrosion inhibitor and heat treatment salt in metallurgical processes.
• In the chemical synthesis of other nitrate salts, dyes, and pharmaceutical intermediates.
• As a food preservative (E251) in cured meats, though this requires specific food-grade certification.
• In waste water treatment and as a component in heat transfer fluids.

Quality Control

Our Sodium Nitrate is produced under a stringent quality management system to ensure batch-to-batch consistency and reliability. We offer various grades, including technical and purified, with specifications tailored to meet the demands of diverse industrial applications. Certificates of Analysis (COA) documenting key parameters such as assay, impurity profiles, and physical properties are provided with every shipment to guarantee compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials. Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption. Store away from strong alkalis and organic solvents. Recommended storage temperature: 15-25°C.
