Sodium nitrate is being utilized as a nitrogen-rich fertilizer component, primarily in agricultural regions where soil nutrient replenishment is essential for yield optimization. Usage is particularly pronounced in Asia Pacific and Latin America, where population growth and arable land constraints are driving the adoption of nitrate-based fertilizers. According to the Food and Agriculture Organization, nitrogenous fertilizer use has continued to rise, influencing market demand for compounds such as sodium nitrate.
In the food industry, sodium nitrate is being incorporated as a curing agent and preservative, particularly in processed meats. Its function in inhibiting microbial growth and maintaining product quality is being acknowledged under strict regulatory standards. The USA Food and Drug Administration and the European Food Safety Authority permit its use within specified limits to ensure food safety while maintaining efficacy.
Industrial applications are expanding with sodium nitrate being deployed in explosives manufacturing, metal treatment, glass production, and solar thermal storage. In concentrated solar power systems, sodium nitrate-based molten salt is being utilized for its excellent thermal retention capabilities. As reported by the International Renewable Energy Agency, CSP adoption is gaining traction in countries such as Spain, India, and the United Arab Emirates, where grid-scale energy storage solutions are being prioritized.
Producers are investing in purification technologies to meet the performance standards of specialty applications, including electronics and pharmaceuticals. The market is characterized by stable supply from key mineral sources in Chile and China, where natural deposits are refined to meet industrial and agricultural specifications.
The sodium nitrate market is expected to continue expanding as downstream users seek reliable, multifunctional chemical inputs to meet global performance, sustainability, and productivity targets through 2035.
Industrial grade sodium nitrate is estimated to account for approximately 72% of the global sodium nitrate market share in 2025 and is projected to grow at a CAGR of 6.6% through 2035. This grade is extensively used in nitrogen-based fertilizer production, thermal energy storage, and as an oxidizing agent in explosives and pyrotechnics.
Large-scale demand continues to be driven by agricultural and mining sectors in countries such as China, India, and Brazil.
