Strontium fluoride is widely used in the production of optical components, particularly for lenses, windows, and prisms in the ultraviolet (UV) and infrared (IR) regions due to its transparency in these wavelengths. It is also employed in the manufacturing of specialized glass and ceramics, where it enhances durability and thermal stability. In the field of electronics, it serves as a dielectric material in capacitors and other components. Additionally, strontium fluoride is utilized in certain types of phosphors for lighting and display technologies, contributing to improved brightness and efficiency. Its application extends to nuclear reactors, where it acts as a neutron detector due to its ability to interact with neutron radiation.

In the medical field, strontium fluoride is incorporated into oral care products such as toothpaste and mouthwash to strengthen teeth and prevent decay. It inhibits bacterial growth and promotes remineralization of tooth enamel. Furthermore, research explores its use in biomaterials for developing artificial bones or implants, as it supports bone and surrounding tissue growth.
