· Mg4 Ta2 Sb2 O12

Mg₄Ta₂Sb₂O₁₂ is a complex ternary oxide semiconductor composed of magnesium, tantalum, and antimony. This is a research-phase material studied primarily for its electronic and photonic properties, belonging to the family of mixed-metal oxides that can exhibit semiconducting behavior useful in solid-state device applications. The material's notable characteristic is the combination of tantalum (a high-refractive-index, chemically stable element) with antimony oxides in a magnesium host lattice, which may yield interesting optical absorption, band structure, or ionic conductivity features not readily available in simpler binary compounds.

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.
