· HfHgO3

HfHgO3 is an experimental ternary oxide semiconductor combining hafnium and mercury oxides, representing a rare composition in the perovskite-related oxide family. This material remains primarily in research phase, with potential applications in advanced optoelectronic and high-permittivity dielectric devices where the combined properties of hafnium and mercury oxides might enable novel functionality. Its high density and rigid elastic structure suggest interest in specialized microelectronics or radiation-detection applications, though industrial adoption is limited and material synthesis and phase stability require further development.

Export Control

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
