Strontium carbonate a mineral, strontium carbonate is prepared synthetically in one of two manners. First of which is from naturally occurring celestine also known as strontium sulfate (SrSO) or by using soluble strontium salts by the reaction in solution with a soluble carbonate salt (usually sodium or ammonium carbonates). For example if sodium carbonate was used in solution with strontium nitrate: Sr(NO) + NaCO → SrCO + 2 NaNO . The most common use is as an inexpensive colorant in fireworks. Strontium and its salts emit a brilliant red color in flame. Unlike other strontium salts, the carbonate salt is generally preferred
Lithium nitrate Lithium nitrate Lithium nitrate is an inorganic compound with the formula LiNO. It is the lithium salt of nitric acid (an alkali metal nitrate). The salt is deliquescent, absorbing water to form the hydrated form, lithium nitrate trihydrate. Its eutectics are of interest for heat transfer fluids. It is made by treating lithium carbonate or lithium hydroxide with nitric acid. This deliquescent colourless salt is an oxidizing agent used in the manufacture of red-colored fireworks and flares. The hydrated form, lithium nitrate trihydrate, has an extremely high specific heat of fusion, 287 (± 7) J/g, and hence can be used
