· JVASP-35057· KMgAs

KMgAs is an intermetallic ceramic compound combining potassium, magnesium, and arsenic in a crystalline structure. This material belongs to the family of ternary chalcogenide and pnictide ceramics, which are primarily of research interest rather than established commercial use. KMgAs and related compounds are investigated for potential applications in optoelectronics, thermoelectrics, and semiconductor research, where the combination of light elements with arsenic offers possibilities for bandgap engineering and thermal management, though the arsenic content and chemical stability present practical challenges for widespread industrial adoption.

Regulatory Screening

Environmental

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.
