Sodium nitrate, melting point of 306.8℃, density of 2.257 g/cubic centimeter (20℃), colorless transparent or white microstrip yellow rhombic crystal. Its taste is bitter and salty, easily soluble in water and liquid ammonia, slightly soluble in glycerol and ethanol, easy delixing, especially when containing a very small amount of sodium chloride impurities, sodium nitrate delixing is greatly increased. When dissolved in water, the solution temperature decreases and the solution becomes neutral. When heated, sodium nitrate readily decomposes into Sodium Nitrite and oxygen. Sodium nitrate can aid combustion and must be stored in a cool and ventilated place. Oxidizing, friction or impact with organic matter can cause combustion or explosion.

Sodium nitrate has always been one of the important Production raw materials of the group's civil explosive industry, and as one of the important chemical raw materials, sodium nitrate is widely used. Among them, 1 ton of industrial explosives consumes about 0.1 tons of sodium nitrate, which is the main raw material second only to ammonium nitrate in the manufacture of industrial explosives.

In recent years, the gap between the import and Export volume of sodium nitrate products in China has been high, and the export volume is far greater than the import volume. In 2023, China's Sodium Nitrate Imports were 196.75 tons, still at a low level, while exports had grown rapidly to 51,800 tons.

A large number of foreign sodium nitrate into the Chinese market, which has a large impact on China's sodium nitrate manufacturers, therefore, China's sodium nitrate manufacturers to improve their own production capacity and Quality.

China's sodium nitrate manufacturers mainly use Soda Ash method and borax method to produce sodium nitrate, soda ash method uses waste gas, comprehensive utilization of resources, the pollution to the environment is relatively small; The sodium nitrate industry business report predicts that the recent market demand for sodium nitrate will not have much growth.

In the past three years, the production situation of China's sodium nitrate industry is not optimistic, and the production capacity and output are declining. As China's sodium nitrate enterprises strengthen production management, improve the process flow, and adjust the industrial structure; In the next five years, China's sodium nitrate industry production will show a slight recovery, and it is expected that by 2024, China's sodium nitrate industry output will reach 957,500 tons.
