· JVASP-33802· TeI2

Tellurium dioxide (TeI₂) is an inorganic ceramic compound combining tellurium and iodine, belonging to the broader family of halide and chalcogenide ceramics. This material is primarily of research and specialized industrial interest rather than a commodity engineering ceramic, with applications emerging in optics, radiation detection, and advanced electronic devices where its unique electronic and thermal properties can be exploited. TeI₂ is notable within the tellurium compound family for its potential use in infrared optics, scintillator materials for nuclear and particle detection, and as a semiconductor in niche electronic applications where conventional silicates or oxides are insufficient.

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.
