· GdAlO3

Gadolinium aluminate (GdAlO3) is a rare-earth perovskite ceramic compound combining gadolinium oxide with aluminum oxide in a crystalline structure. It is primarily of interest as a substrate material and in research contexts for high-temperature applications, particularly in thin-film technologies and as a lattice-matched platform for epitaxial growth of functional oxides and superconductors. Its thermal stability, chemical compatibility with oxide films, and relatively low thermal expansion mismatch compared to common superconducting materials make it valuable in materials research, though it remains less widely deployed than more established alternatives like yttria-stabilized zirconia or magnesium oxide in industrial production.

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.
