· HgSnO3

HgSnO3 is an experimental ternary oxide semiconductor composed of mercury, tin, and oxygen, belonging to the perovskite or perovskite-related oxide family. This compound remains primarily in the research phase, with interest driven by its potential as a wide-bandgap semiconductor for optoelectronic and sensing applications, though toxicity concerns associated with mercury chemistry limit practical industrial adoption. Researchers explore HgSnO3 variants to understand lead-free perovskite alternatives and mercury-containing oxide semiconductors, but it has not achieved widespread engineering deployment compared to more established tin oxide or lead-based systems.
