· JVASP-135093· Sr2HfO3

Sr₂HfO₃ is a strontium hafnate ceramic compound belonging to the perovskite family of oxides, characterized by a double-perovskite crystal structure. This material is primarily investigated in research contexts for high-temperature structural applications and as a thermal barrier coating candidate, where its hafnate base provides excellent oxidation resistance and refractory properties. Engineers consider Sr₂HfO₃ for extreme-environment applications requiring chemical stability and thermal durability beyond conventional oxide ceramics, particularly in aerospace and power generation sectors exploring next-generation materials.

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.
