Key Characteristics
High NaNO₃ content - Up to 99.7% on a dry basis, providing a concentrated nitrate source for industrial formulations.
Controlled impurities - Chloride, sodium nitrite, sodium carbonate, water-insoluble matter, and moisture are specified to support consistent downstream processing.
Stable crystalline form - The white crystalline/prilled form is suitable for dry handling, weighing, blending, and industrial dosing.
High thermal stability - Sodium nitrate melts at approximately 308°C and undergoes thermal decomposition at higher temperatures, making its thermal behavior relevant to glass, metallurgy, and heat-transfer applications.
Water soluble - Its high water solubility supports applications requiring rapid dissolution or preparation of aqueous nitrate solutions.
Packaging, Storage & Transportation
Standard packaging options include:
25 kg PP/plastic woven bags with PE inner liners
50/500/1000 kg flexible freight bags
Kraft paper bags or other packaging upon agreement
For export orders, packaging can be matched to the buyer's handling equipment, container-loading requirements, and destination regulations.
Storage: Keep in a dry, well-ventilated area and protect from rain, moisture, and direct sunlight. Sodium nitrate is an oxidizing substance and should be kept away from combustible or incompatible materials, including organic compounds, sulfur, and reducing agents.
Transportation: Sea, rail, and road, subject to applicable dangerous-goods requirements.
