Product Description





Strontium Fluoride (SrF2) is one of the most important alkaline-earth fluorides. It has many physical properties, such as low energy phonon, high ionization, high resistance coefficient and good anion conductivity. It has been widely used in light-emitting devices, optical imaging, biomarkers, anion conductors and other fields. Compared with oxide and calcium fluoride, strontium fluoride has lower phonon energy, higher thermal conductivity and negative thermal optical coefficient, especially negative thermal optical coefficient, which can compensate the thermal lens effect in the process of laser oscillation. Strontium fluoride has promoted the research of optical materials and the improvement of optical instruments with its unique material structure and properties




  • Poorly soluble in water, ethanol and methanol
  • High conductivity and optical properties similar to calcium fluoride
  • Can transmit ultraviolet and infrared waves
  • Very dangerous to the health, poisonous when inhaled or ingested and in low concentration can cause irritation to skin and eyes.
  • Not flammable



  • UV and VUV spectroscopy
  • Manufacture optical materials for different devices, like glasses, windows and lenses
  • Intermediate infrared laser matrix material
