Strontium peroxide is an inorganic chemical compound of strontium from the group of peroxides .

Extraction and presentation

Strontium peroxide can be obtained by reacting oxygen or hydrogen peroxide with strontium oxide .

The octahydrate is also obtained by reacting strontium nitrate with sodium peroxide .
