Lithium nitrate is an inorganic compound with the formula LiNO3. The compound is deliquescent, absorbing water to form the hydrated form, lithium nitrate trihydrate. Its eutectics are of interest for heat transfer fluids.
Lithium nitrate is a powerful oxidizer. When mixed with a combustible material and ignited, it burns with a red flame.
Lithium nitrate is a colorless solid, soluble in water.
The hydrated form, lithium nitrate trihydrate, has an extremely high specific heat of fusion, 287 (± 7) J/g, and hence can be used for thermal energy storage at its melt temperature of 303.3 K.
Lithium nitrate is sold by chemical suppliers.
Lithium nitrate can be easily and safely synthesized by reacting nitric acid and lithium carbonate.
- Li2CO3 + 2 HNO3 → 2 LiNO3 + H2O + CO2
If available lithium hydroxide can also be used, although the neutralization reaction is very exothermic, so the solution needs to be cooled during the reaction.
- LiOH + HNO3 → LiNO3 + H2O
Never use lithium metal as it will catch fire and may even explode!
- Red-colored fireworks and flares
- Heat storage
Lithium nitrate, like most lithium compounds can be toxic to the body when ingested by targeting the central nervous system, thyroids, kidneys, and cardio-vascular system.
It is a powerful oxidizer and must be kept away from combustible materials.
In closed glass or plastic bottles, away from acids and flammable materials.
Lithium nitrate can be converted to an insoluble lithium compound and recycled. While it may be used as fertilizer to a degree, lithium is expensive and it's best to recycle it.
