What Sodium Nitrate Is
Sodium nitrate is a white crystalline solid, highly soluble in water, and non-hygroscopic, meaning it does not absorb moisture from the air. Its chemical stability under normal conditions makes it a versatile compound suitable for various applications. Its solubility increases with temperature, allowing for easy dissolution in industrial processes requiring aqueous solutions.
Synonyms:
E251 , niter , nitratine , Soda niter , cubicniter, nitrateofsoda , CHILE SALPETER , Sodium nitrate , Natriumnitrat
Chemical Properties
Sodium nitrate is an ionic compound composed of sodium cations (Na⁺) and nitrate anions (NO₃⁻). It has a molar mass of 84.994 g/mol and a 2.257 g/cm³ density. The compound decomposes upon heating, releasing oxygen and leaving behind sodium nitrite, which can further decompose to sodium oxide and nitrogen dioxide if the temperature is sufficiently high.
Reactivity and Uses
Sodium nitrate is a potent oxidizing agent, which is why it finds use in the manufacture of explosives where rapid oxidation is necessary. Its oxidizing power also makes it effective in glass and ceramics production to enhance the processing of materials and improve product characteristics.

Production Technology of Sodium Nitrate
Natural Extraction (Chilean Method)
Historically, sodium nitrate was obtained from natural deposits, primarily found in Chile, hence the name “Chile saltpeter.”
- Mining: Large deposits of sodium nitrate were mined from the nitrate-rich caliche ore found in the Atacama Desert.
- Refining: The mined ore was refined to remove impurities. This involved crushing the caliche and leaching it with water to dissolve the sodium nitrate.
- Crystallization: The solution was then subjected to a crystallization process. As the water evaporated, sodium nitrate crystals formed.
- Purification: The crystals were further purified through washing and recrystallization to achieve the desired purity levels.
Though historically significant, this method has largely been replaced by synthetic production methods due to limited natural reserves and environmental concerns.
Synthetic Production
The modern production of sodium nitrate is primarily synthetic, involving the reaction of nitric acid with sodium carbonate or sodium hydroxide.
- Step 1: Production of Nitric Acid
- Nitric acid is produced industrially by the Ostwald process.
- Ammonia is oxidized to nitric oxide (NO) using a platinum catalyst at high temperatures.
- The nitric oxide is oxidized to nitrogen dioxide (NO₂), which is then absorbed in water to form nitric acid (HNO₃).
- Step 2: Reaction with Sodium Carbonate or Sodium Hydroxide
- Nitric acid is reacted with sodium carbonate (Na₂CO₃) or sodium hydroxide (NaOH) to produce sodium nitrate.
- The reaction with sodium carbonate is as follows:
- 2HNO3+Na2CO3→2NaNO3+H2O+CO2
- Alternatively, the reaction with sodium hydroxide is:
- HNO3+NaOH→NaNO3+H2O
- Crystallization and Purification
- The resulting solution contains sodium nitrate, which is then crystallized out of the solution.
- Impurities are removed by filtration, and the crystals are dried.
- Further purification may involve recrystallization or additional washing, depending on the required purity level for specific applications.
- Quality Control
- Quality control measures are implemented throughout the manufacturing process to ensure the purity and consistency of the sodium nitrate produced.
- The final product is tested for various parameters, including purity, chemical composition, and physical properties.
