Strontium nitrate is an inorganic compound with the formula Sr(NO3)2. It is available in anhydrous and hydrated forms. This compound is used as a red colorant and oxidizer in pyrotechnics.
Strontium nitrate, when mixed with a powdered flammable material, like aluminium, will rapidly burn with a red flame, which allows the salt to be used in pyrotechnic mixtures.
- Sr(NO3)2 + 2 Al → Al2O3 + SrO + N2
Heating strontium nitrate above 5-600 °C will cause it to decompose, releasing nitrogen dioxide and oxygen.
- Sr(NO3)2 → SrO + 2 NO2 + ½ O2
Strontium nitrate is a white solid, very soluble in water, but less soluble in organic solvents.
Strontium nitrate is sold by chemical suppliers.
Can also be extracted from red flame producing fireworks, though it's a lot of work.
- 2 HNO3 + SrCO3 → Sr(NO3)2 + H2O + CO2
- Make red flame
- Source of strontium ions
- Make anti-skin irritation topic
The human body absorbs strontium as if it were its lighter counterpart calcium. Because the elements are chemically very similar, strontium do not pose a significant health threat.
Strontium nitrate can aid in eliminating and lessening skin irritations. When mixed with glycolic acid, strontium nitrate reduces the sensation of skin irritation significantly better than using glycolic acid alone.
Strontium nitrate should be stored in plastic or glass containers or bottles, away from acids and any flammable materials.
Strontium has low toxicity, and doesn't require special neutralization or disposal. Could be used as soil fertilizer, though it's expensive for such use.
