· Hg2 I2 Br2

Hg₂I₂Br₂ is a mixed-halide mercury compound semiconductor belonging to the family of mercury halide materials, which have been investigated for optoelectronic and radiation detection applications. This is primarily a research-phase material rather than a commodity product; mercury halide semiconductors are studied for their potential in X-ray and gamma-ray detection systems, infrared sensing, and other specialized photonic applications where their unique band structure and high atomic number offer advantages. The mixed halide composition (combining iodide and bromide) allows tuning of electronic properties compared to binary mercury halides, making it of interest in materials engineering for next-generation radiation detector development.

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.
