· ErTaO3

ErTaO3 is a rare-earth tantalate ceramic compound combining erbium oxide with tantalum pentoxide, belonging to the family of complex oxide perovskites and related structures. This material is primarily of research and specialized engineering interest, investigated for high-temperature applications, optical devices, and advanced ceramic coatings where its thermal stability and rare-earth properties are leveraged. ErTaO3 represents an emerging class of materials designed for next-generation applications in aerospace thermal management, photonics, and solid-state device substrates where conventional ceramics reach performance limits.

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.
