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
Guanidine nitrate Guanidine nitrate Guanidine nitrate is the chemical compound with the formula [C(NH)]NO. It is a colorless, water-soluble salt. It is produced on a large scale as high energy fuel used as gas generator and solid rocket propellant applications. Its more official name is guanidinium nitrate, but the incorrect term guanidine nitrate is widely used. Although it is the salt formed by neutralizing guanidine with nitric acid, guanidine nitrate is produced industrially by the reaction of dicyandiamide (or calcium salt) and ammonium nitrate. It has been used as a monopropellant in the Jetex engine for model airplanes. It is attractive because
