· JVASP-69184· BaHgSe4

BaHgSe₄ is a ternary chalcogenide ceramic compound combining barium, mercury, and selenium—a member of the rare earth and heavy metal selenide family used primarily in research contexts. This material is investigated for infrared optics and nonlinear optical applications due to its wide transparency window in the infrared spectrum and potential for frequency conversion devices. While not yet established in mainstream industrial production, BaHgSe₄ represents an emerging candidate for specialized photonic and sensing systems where conventional semiconductors or transparent ceramics fall short.

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.
