Sr3Al2Si2
metal· JVASP-15728· Sr3Al2Si2
Sr3Al2Si2 is an intermetallic compound combining strontium, aluminum, and silicon—a material class of interest in advanced ceramics and lightweight structural applications research. While not yet widely commercialized in high-volume engineering, strontium aluminosilicates are explored in thermal management, refractory applications, and as precursor phases in composite development due to their thermal stability and moderate stiffness characteristics. Engineers may consider this material family for niche applications where thermal cycling resistance and reduced density are advantageous over conventional monolithic ceramics.

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.
