· JVASP-58925· Hg2P3Br

Hg2P3Br is a mixed-metal halide ceramic compound containing mercury, phosphorus, and bromine elements. This is a research-phase material studied primarily in solid-state chemistry and materials science rather than established industrial production, with potential applications in semiconducting or photonic devices that exploit halide perovskite-like structures. The material belongs to an emerging class of metal halides being investigated for optoelectronic properties and may offer alternative pathways for devices where lead-free or mercury-based chemistries are explored, though commercial viability and toxicity considerations remain significant research questions.
