· JVASP-121899· Sr2YAlCr2O7

Sr2YAlCr2O7 is a complex oxide ceramic belonging to the pyrochlore family, combining strontium, yttrium, aluminum, and chromium oxides in a layered crystalline structure. This material is primarily investigated in research contexts for high-temperature applications, particularly as a thermal barrier coating (TBC) system or as a candidate material for advanced refractory applications where chemical stability and thermal cycling resistance are critical. Compared to conventional TBC materials like yttria-stabilized zirconia (YSZ), complex oxides of this type offer potential advantages in environments involving oxidizing conditions and interactions with molten salts or corrosive phases, making them of interest for next-generation aerospace propulsion and industrial furnace applications.

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.
