· PbWO3

Lead tungstate (PbWO₃) is a dense inorganic ceramic compound that combines high atomic-number lead with tungstate chemistry, creating a material with strong radiation interaction properties. It is primarily used in high-energy physics and medical imaging applications where its high density and scintillation characteristics enable efficient detection of gamma rays and X-rays; compared to alternatives like BGO (bismuth germanate) or LSO (lutetium orthosilicate), PbWO₃ offers a favorable balance of fast response time and compact geometry, though it remains a specialized material predominantly found in research and industrial detector systems rather than commodity applications.

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.
