· JVASP-155563· Ca2HgTe2F2

Ca2HgTe2F2 is a complex fluoride ceramic compound combining calcium, mercury, tellurium, and fluorine—a rare composition that places it at the intersection of halide perovskite and heavy-element ceramics research. This material remains primarily in the experimental phase, investigated for potential applications in optoelectronic and photonic devices where the combination of heavy cations (mercury, tellurium) and fluoride ligands may enable unique optical or electronic properties distinct from conventional ceramics.

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.
