</table> Sodium nitrate is a type of salt which has long been used as an ingredient in explosives, and has been mined extensively for that purpose. The world's largest deposits were in the Atacama desert of Chile, and these were mined for over a century, until the 1940s. It has antimicrobial properties when used as a food preservative.
