Strontium nitrate Strontium nitrate Strontium nitrate is an inorganic compound made of the elements strontium and nitrogen with the formula Sr(NO). This colorless solid is used as a red colorant and oxidizer in pyrotechnics. Strontium nitrate is typically generated by the reaction of nitric acid on strontium carbonate. Like many other strontium salts, strontium nitrate is used to produce a rich red flame in fireworks and road flares. The oxidizing properties of this salt are advantageous in such applications. Strontium nitrate can aid in eliminating and lessening skin irritations. When mixed with glycolic acid, strontium nitrate reduces the sensation of skin irritation
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
