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
Zirconium nitrate Zirconium nitrate Zirconium nitrate is a volatile anhydrous transition metal nitrate of zirconium with formula Zr(NO). It has alternate names of zirconium tetranitrate, or zirconium(IV) nitrate. It has a UN number of UN 2728 and is class 5.1, meaning oxidising substance. Anhydrous Zirconium nitrate can be made from zirconium tetrachloride reacting with dinitrogen pentoxide. ZrCl + 4 NO → Zr(NO) + 4ClNO The product can be purified by sublimation in a vacuum. A contaminating substance in this is nitronium pentanitratozirconate. (NO)Zr(NO). Zirconium nitrate pentahydrate Zr(NO).5HO can be formed by dissolving zirconium dioxide in nitric acid and then evaporating the solution
