Lithium nitrate is a colorless deliquescent powder, enthalpy of fusion 24.90 kJ/mol; can be prepared by reaction of HNO3 with LiOH or Li2CO3, followed by evaporation to dryness and then heating at ~200°C in vacuum; used in ceramics, pyrotechnics, molten salt baths, rocket propellants, refrigerators.

용도Lithium nitrate can be used in special pyrotechnic devices to give a red flame. It may also be used in combination with other salts, particularly nitrates, to produce low-melting fused salt mixtures.

일반 설명A white to light yellow colored crystalline solid. Denser than water. Contact with the material may cause irritation to skin, eyes, and mucous membranes. May be toxic by ingestion. May cause the acceleration of the burning of combustible materials. Prolonged exposure to heat or flames may result in an explosion.

Lithium nitrate is readily prepared industrially or in the laboratory by the reaction of lithium hydroxide or lithium carbonate with nitric acid. The resulting solution is evaporated and the solid is dried to obtain anhydrous lithium nitrate. Lithium nitrate is very soluble in water. The compound absorbs moisture from the air. Below about 30 °C it crystallizes from solution as lithium nitrate trihydrate; above that temperature the anhydrous material precipitates although the question of the existence of a half-hydrate is not entirely settled.
