· SiHgO3

SiHgO3 is an inorganic ceramic compound containing silicon, mercury, and oxygen. This is a research-phase material rather than a widely commercialized ceramic; it represents an experimental composition within the broader family of mixed-metal oxides with potential applications in specialized electronic, optical, or structural contexts. The inclusion of mercury makes this material notable for its density and potential electronic properties, though practical adoption would require careful evaluation of toxicity, stability, and manufacturing feasibility compared to conventional oxide ceramics.
