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
Zinc nitrate to zinc oxide has also been used for the generation of various ZnO based structures, including nanowires. It can be used as a mordant in dyeing. An example reaction gives a precipitate of zinc carbonate: Zinc nitrate Zinc nitrate is an inorganic chemical compound with the formula Zn(NO) . This white, crystalline solid is highly deliquescent and is typically encountered as a hexahydrate Zn(NO)•6HO. It is soluble in both water and alcohol. Zinc nitrate is usually prepared by dissolving zinc in nitric acid, this reaction is concentration dependent, with a reaction in concentrated acid also forming ammonium nitrate: On heating,
