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
Rubidium nitrate Rubidium nitrate Rubidium nitrate is an inorganic compound with the formula RbNO. This alkali metal nitrate salt is white and highly soluble in water. Rubidium nitrate is a white crystalline powder that is highly soluble in water and very slightly soluble in acetone. In a flame test, RbNO gives a mauve/light purple colour. Rubidium compounds have very few applications. Like caesium nitrate, it is used in infrared radiation producing pyrotechnic compositions as a colorant and an oxidizer, e.g. in decoys and illumination flares. It is also used as a raw material for preparation of other rubidium compounds and rubidium metal,
