Formation of Strontium Oxide
2Sr + O2 → 2SrO
Overview
Strontium metal burns in oxygen with a characteristic crimson-red flame to produce strontium oxide. This is a vigorous reaction due to strontium's high reactivity as an alkaline earth metal. The red color is exploited in pyrotechnics.

Everyday Example
Red fireworks and signal flares often contain strontium compounds that produce their intense red color from strontium emission spectra.
Industrial Importance
Strontium oxide is used in the production of strontium ferrite magnets, in cathode ray tubes, and in specialty glass for television screens.
