Sodium nitrate is one of the earliest nitrogen fertilizer, can be used for acid soil, especially suitable for root crops, such as

sugar beet and radish. In the end of the 19th century to the early 20th century, Chile exploited sodium nitrate mining in large

scale as nitrogen fertilizer for the world. Farmers in Xinjiang uygur autonomous region in China digged desert surface soil contain

NaNO3 to plant grape fruits, and the fertilizer effect is remarkable.

Sodium nitrate can be used to make nitrate, picric acid, explosives, mineral raw materials, dyes, osmotic pressure regulator in medicine

and other nitrogen compounds, it also can be used in glass, metallurgy, light industry and other industrial sectors.

In glass industry, it can be used for the production of various kinds of glass and its products of defoaming agent, decoloring agent, clarifying

agent and oxidation solubilizer. Enamel industry uses it as oxidant, solubilizer, and to make enamel powder. Machinery industry uses it as metal

cleaner, dispensing black metallic blue agent. Metallurgical industry uses it for steel and aluminum alloy heat treatment. Light industry uses it as

combustion improver of cigarettes. Pharmaceutical industry uses it as a medium of penicillin.

It can be reduction by bacteria into sodium nitrite in meat, which results in color protection and bacteriostatic effect, and can be used as food color fixative in China.

It also can be used as decolorizing agent of molten caustic soda and analytical reagent.
