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

In allusion to the composition, being a NITRATe. Nitratine, sodium nitrate, is found as an efflorescence in hot dry regions. As of 2021 there are now IMA–CNMNC approved mineral symbols (abbreviations) for each mineral species, useful for tables and diagrams. Warr, L.N. (2021). IMA–CNMNC approved mineral symbols.

Residual water-soluble surface deposits in extremely arid deserts. Nitrates occur in clay rich caliche deposits replenished by occasional desert thunderstorms which fix N2 from the air. Confidence Hills, southern Death Valley. Atacam desert, Chile. Link to MinDat.org Location Data. Named after its composition of containing nitrates.

Nitratine, along with Niter, are unusual minerals belonging to the nitrates group. These two nitrate minerals can be visually indistinguishable, with the ancient term Niter used to describe both Niter and Nitratine. Nitratine is actually the more prevalent and economically important member of …

Nitratine or soda niter is one of the few nitrate minerals that is available on the mineral markets. Nitrates are not all that commonly found due to their general ease in dissolving in water. In fact some solid nitrate crystals will even become liquid by removing water from the moisture in the air, a process called deliquescence .

Chemistry: (1) Identified by correspondence of optical data and X-ray powder pattern with that of synthetic material. Occurrence: Principally in bedded deposits formed in playas; in caves, deposited from seeping groundwater leaching nitrates from overlying rocks, especially in very dry and cold climates.

Nitratine, also known as cubic nitre or soda niter, is a mineral, the naturally occurring form of sodium nitrate, NaNO 3. Nitratine crystallizes in the trigonal system, but rarely occurs as well formed crystals. It is isostructural with calcite. The typical form is as coatings of white, grey to yellowish brown masses.
