· Mg1 Al2 S4

Mg₁Al₂S₄ is a ternary semiconductor compound combining magnesium, aluminum, and sulfur—a member of the I-III-VI₂ semiconductor family related to II-VI materials like zinc blende structures. This is a research-phase material with potential applications in optoelectronics and photovoltaics where wide bandgap semiconductors are needed; it represents an emerging alternative to more established compounds like GaAs or CdTe, offering the possibility of tuning electronic properties through magnesium-aluminum composition control while leveraging abundant, lower-toxicity constituent elements.

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.
