Sodium nitrate is the chemical compound with the formula Na N O. 3. This alkali metal nitrate salt is also known as Chile saltpeter (large deposits of which were historically mined in Chile) [4] [5] to distinguish it from ordinary saltpeter, potassium nitrate. The mineral form is also known as nitratine, nitratite or soda niter .
Nitratine. Nitratine or nitratite, also known as cubic niter (UK: nitre ), soda niter or Chile saltpeter (UK: Chile saltpetre ), is a mineral, the naturally occurring form of sodium nitrate, NaNO 3. Chemically it is the sodium analogue of saltpeter. Nitratine crystallizes in the trigonal system, but rarely occurs as well-formed crystals.
Also called Pink curing salt #2. It contains 6.25% sodium nitrite, 4% sodium nitrate, and 89.75% table salt. The sodium nitrate found in Prague powder #2 gradually breaks down over time into sodium nitrite, and by the time a dry cured sausage is ready to be eaten, no sodium nitrate should be left.
The María Elena nitrate plant is the last nitrate works still in operation in the world. It was initially named Coya Norte, but was renamed María Elena (after his wife Mary Ellen Condon) [1] by its founder Elias Anton Cappelen Smith. [1] [2] [3] It is located in the commune of the same name, in Chile, 220 km northeast of Antofagasta .
Concern of exhaustion was ameliorated by the discovery of a new Peruvian resource: sodium nitrate, also called Chile saltpetre. After 1870, the use of Peruvian guano as a fertilizer was eclipsed by Chile saltpetre in the form of caliche (a sedimentary rock) extraction from the interior of the Atacama Desert, close to the guano areas.

Salitre was an important source of export revenue for Chile until World War I, when Europe began to produce both nitrates industrially in large quantities. [ 21 ] The deposits contain an average of 7.5% sodium nitrate, as well as sodium sulfate (18.87%), sodium chloride (4.8%), and smaller amounts of potassium, calcium, magnesium, borate ...
The use of Nitratine or Chilean Saltpeter once an important source of nitrates for fertilizer and other chemical uses including gunpowder and fireworks.. The commencement of the export of nitrates to the Europe and the US in the 1830s marked the most important milestone in the history of the nitrate industry and brought consequences for the economies of the three countries sharing the Atacama ...
Caliche sangriento (i.e. Bloody Nitrate) is a Chilean movie of 1969 and the first one directed by Helvio Soto. The plot takes place in 1879 through 1880 during the War of the Pacific, when Chile, Bolivia and Peru fought over control of the sodium nitrate deposits in the Atacama desert. The film decries the cruelty and absurdity of war and the ...
