· HgTaO3

HgTaO3 is a complex oxide ceramic compound containing mercury, tantalum, and oxygen, belonging to the family of functional ceramics with potential ferroelectric or multiferroic properties. This material is primarily of research interest rather than established in mainstream industrial production, with investigations focused on its electrical, magnetic, and dielectric characteristics for next-generation electronic and photonic applications. The incorporation of mercury into a tantalate framework makes it notable in the context of exploring novel perovskite or perovskite-derived structures, though practical deployment is limited by processing challenges and mercury volatility at elevated temperatures.
