Used in the production of phosphors and luminescent materials, particularly in cathode ray tubes (CRTs) for older televisions and computer monitors to enhance the brightness of red light.

Commonly used in oral care products, such as toothpaste for sensitive teeth, due to its ability to occlude dentin tubules and block pain signals from exposed dentin, reducing sensitivity to hot and cold stimuli.

Employed in pyrotechnics to produce bright red flames in fireworks and signal flares.

Serves as a source of strontium in laboratory settings for chemical synthesis and in the preparation of other strontium compounds.

Utilized in biological and biochemical research, such as studies on muscle and nerve cell functions, where strontium ions can substitute for calcium ions in certain physiological processes.

Occasionally used in medical studies involving bone metabolism, as strontium can influence bone density.
