Quick Summary

Strontium oxide (SrO) is an oxide of strontium, specifically the crystalline monoxide that resembles lime and barium monoxide. Strontium itself is a chemical element and an alkaline-earth metal. It is a soft, silvery metal that quickly reacts with air.12

While strontium compounds have limited commercial value compared to similar calcium or barium compounds, strontium oxide is a key component in the chemistry of strontium. Strontium compounds are notable for producing a brilliant crimson color in fireworks, flares, and tracer ammunition. Strontium oxide is also used in some industrial processes, such as the extraction of sugar from molasses.2
