· JVASP-9073· SrAs

Strontium arsenide (SrAs) is a binary ceramic compound belonging to the III-V semiconductor family, characterized by ionic bonding between strontium and arsenic. This material is primarily of research and developmental interest rather than established in high-volume production, with investigations focused on its potential in optoelectronic and thermoelectric applications due to its wide bandgap and thermal properties.

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.
