BaWO4
ceramic· JVASP-11753· BaWO4
Barium tungstate (BaWO₄) is a dense inorganic ceramic compound belonging to the scheelite family of tungstates, characterized by its high atomic number constituents that confer excellent radiation absorption properties. It is primarily used in medical imaging (X-ray scintillation detectors), high-energy physics instrumentation, and specialized optical applications where dense, efficient photon conversion is required. BaWO₄ is valued over lighter alternatives because its tungsten content enables superior stopping power for gamma rays and X-rays while maintaining good scintillation efficiency, making it the material of choice for precision radiation detection systems in both clinical and research settings.

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.
