The solubility is increased significantly if the water is saturated with carbon dioxide, to 0.1 g per 100 ml.

In the "black ash" process, celesite is roasted with coke at 1100–1300 °C to form strontium sulfide.

Strontium and its salts emit a brilliant red color in flame.

It is used for manufacturing color television receivers to absorb electrons resulting from the cathode.

[citation needed] This is the "blue/green" phosphor which is sensitive to frequency and changes from lime green to blue.

The cyanobacteria Calothrix, Synechococcus and Gloeocapsa can precipitate strontian calcite in groundwater.
