· Hg2TeO3

Hg₂TeO₃ is a mercury tellurite ceramic compound belonging to the family of heavy-metal oxide ceramics. This is a research-phase material primarily studied for its optical and electronic properties rather than established commercial production. Mercury tellurite ceramics are investigated for potential applications in infrared optics, nonlinear optical devices, and specialized electronic components where the combination of mercury and tellurium oxides may offer unique optical transmission windows or ferroelectric behavior unavailable in conventional ceramics.
