Formation of Strontium Oxide
2Sr + O2 → 2SrO
Visão geral
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.

Exemplo do cotidiano
Red fireworks and signal flares often contain strontium compounds that produce their intense red color from strontium emission spectra.
Importância industrial
O óxido de estrôncio é utilizado na produção de ferrite de estrôncio para ímanes permanentes, em tubos catódicos de televisão (uso histórico) e em luzes de emergência vermelhas. Os sais de estrôncio produzem a chama vermelha característica dos fogos-de-artifício.
