Strontium peroxide (SrO2) is a whitish inorganic compound and a peroxide of strontium.
Uses
It is an oxidizing agent used for bleaching. It is used in some pyrotechnic compositions as an oxidizer and a vivid red pyrotechnic colorant. It can also be used as an antiseptic and in tracer munitions.
Manufacturing
Strontium peroxide is created by passing oxygen over heated strontium oxide. In a manner similar to barium peroxide, SrO2 decomposes to SrO and O2 at temperature, although this temperature is far lower than BaO2. As a consequence, SrO2 is harder to manufacture as the lower temperatures kinetically inhibit the peroxidation reaction on the atomic scale.[3]
