· SrF2

Strontium fluoride (SrF₂) is an inorganic ceramic compound belonging to the fluorite family of ionic ceramics, characterized by high transparency and thermal stability. It is widely used in optical and infrared applications—particularly as window material, lens elements, and detector components in thermal imaging systems and spectroscopy equipment operating in the mid- to far-infrared range. Engineers select SrF₂ over competing optical ceramics (such as CaF₂ or BaF₂) when thermal shock resistance, mechanical stability, and broad transmission windows across infrared wavelengths are critical; it also finds niche applications in nuclear and high-energy physics instrumentation where radiation hardness and scintillation properties are valued.

Regulatory Screening

Environmental

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
