· JVASP-97362· GeBi12O20

Bismuth germanate (GeBi12O20) is an inorganic ceramic compound belonging to the sillenite family of oxides, characterized by a cubic crystal structure with high density. This material is primarily developed for specialized optoelectronic and radiation detection applications, where its high atomic number and strong photorefractive properties enable sensitive detection of ionizing radiation and support electro-optic modulation in optical systems. GeBi12O20 is notable for its potential in scintillator detector arrays and X-ray imaging compared to traditional alternatives, though it remains largely in research and development rather than high-volume industrial production.

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.
