ceramic· JVASP-88447· La2Zr2O7
La2Zr2O7 is a lanthanum zirconium oxide ceramic belonging to the pyrochlore family, valued for its exceptional thermal stability and low thermal conductivity. This material is primarily investigated for thermal barrier coating (TBC) applications in aerospace and power generation, where it serves as an alternative or complement to yttria-stabilized zirconia (YSZ), offering improved phase stability at ultra-high temperatures and potential advantages in long-term durability under extreme thermal cycling conditions.

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.
