Sodium nitrate has also been investigated as a phase-change material for thermal energy recovery, owing to its relatively high melting enthalpy of 178 J/g. [14] [15] Examples of the applications of sodium nitrate used for thermal energy storage include solar thermal power technologies and direct steam generating parabolic troughs. [14]
A second idea, promoted by the guano traders who were eager to participate in the nitrate business, was to create a state monopoly on nitrate sales. An ad hoc senate committee advocated an export tax or, alternatively, a nationalization of the nitrate fields, [ 11 ] : 87–88 which would stop competition between the two fertilizers and bring ...
As a preservative and color fixative, with or without sodium nitrate, in smoked, cured sablefish, smoked, cured salmon, and smoked, cured shad so that the level of sodium nitrite does not exceed 200 parts per million and the level of sodium nitrate does not exceed 500 parts per million in the finished product." [13]
2) is generally supplied by sodium nitrite or (indirectly) by potassium nitrate. Nitrite salts are most often used to accelerate curing and impart a pink colour. [17] Nitrate is specifically used only in a few curing conditions and products where nitrite (which may be generated from nitrate) must be generated in the product over long periods of ...
Sodium nitrate reacts with hydrogen gas: Na + + NO 3 − + 4H 2 → NaOH + NH 3 + 2H 2 O. This removes hydrogen, which poses a fire and explosion hazard and produces ammonia, which is also capable of decomposing organic material, albeit less aggressively than lye. The sodium hydroxide (lye) is consumed by further action of the first reaction.

Tovex is a 50/50 aqueous solution of ammonium nitrate and methylammonium nitrate (sometimes also called monomethylamine nitrate, or PR-M), sensitized fuels, and other ingredients including sodium nitrate prills, finely divided (paint-grade) aluminum, finely divided coal, proprietary materials to make some grades cap sensitive, and thickening agents to enhance water resistance and to act as ...
Glossing gunpowder corns with graphite was already an accepted technique in 1839, [111] and sodium nitrate-based blasting powder had been made in Peru for many years using the sodium nitrate mined at Tarapacá (now in Chile). [112] Also, in 1846, two plants were built in south-west England to make blasting powder using this sodium nitrate. [113]
