LiNO3

Lithium nitrate (LiNO3) is an inorganic compound and the lithium salt of nitric acid. It appears as a white, crystalline solid and is highly soluble in water, forming clear, colorless solutions. The compound is typically handled as a dry salt and stored in sealed containers to prevent moisture uptake.

Chemical preparation: Lithium nitrate can be prepared by neutralizing lithium hydroxide or lithium carbonate with nitric acid. For example, LiOH + HNO3 → LiNO3 + H2O, and Li2CO3 + 2 HNO3 → 2 LiNO3 + CO2 + H2O. The crystals are typically obtained from aqueous solutions by cooling and crystallization.

Uses: As a strong oxidizer, LiNO3 is used in pyrotechnics to promote combustion and produce bright flame colors, and in some solid propulsion formulations as an oxidizing component. It is also employed as a laboratory reagent and, in certain industrial processes, as a chemical intermediate or additive.

Safety: Lithium nitrate is an oxidizer and can intensify fires involving combustible materials. It should be stored away from organic substances and reducing agents, kept in a cool, dry place, and handled with suitable personal protective equipment. Spills should be contained, and contact with skin or eyes should be avoided; dispose of waste according to local regulations.
