· SrWO4

Strontium tungstate (SrWO4) is an inorganic ceramic compound belonging to the scheelite-structure family of tungstate ceramics. It is primarily investigated for use in scintillation detection, luminescence applications, and high-temperature ceramics, where its crystal structure and thermal stability make it attractive for radiation detection systems and specialty optical components. While not as widely deployed as some competing scintillators, SrWO4 offers potential advantages in applications requiring chemically stable, dense ceramic matrices with tunable photoluminescent properties.

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.
