General description
Sodium nitrate is an inorganic sodium salt. Sodium nitrate (Chile saltpeter, NaNO3) is found naturally in abundant amounts in paleogeochemical ores in northern Chile. Sodium nitrate can be obtained from these ores by mining and leaching. NaNO3 can be used as a fertilizer in agricultural fields.
Application
Sodium nitrate may be employed in polyol process for the modification of morphological features of Pt nanoparticles. It may be employed for the modification of natural phosphate (NP) to afford natural phosphate doped with sodium nitrate (NaNO3/NP). NaNO3/NP was used as a catalyst during the synthesis of chalcones.

Paleogeochemical deposits in northern Chile are a rich source of naturally occurring sodium nitrate (Chile saltpeter). These ores are mined to isolate NaNO3 (16-0-0) for use as fertilizer. Coincidentally, these very same deposits are a natural source of perchlorate anion
