Strontium oxalate is a compound with the chemical formula SrC
2O
4. Strontium oxalate can exist either in a hydrated form (SrC
2O
4 · nH
2O) or as the acidic salt of strontium oxalate (SrC
2O
4 · mH
2C
2O
4 · nH
2O).

Use in pyrotechnics

With the addition of heat, strontium oxalate will decompose based on the following reaction:

SrC
2O
4 → SrO + CO
2 + CO

Strontium oxalate is a good agent for use in pyrotechnics since it decomposes readily with the addition of heat. When it decomposes into strontium oxide, it produces a red flame color. Since this reaction produces carbon monoxide, which can undergo a further reduction with magnesium oxide, strontium oxalate is an excellent red flame color producing agent in the presence of magnesium. If it is not in the presence of magnesium, strontium carbonate has been found to be a better option to produce an even greater effect.
