· ScTaO3

ScTaO3 is a complex oxide ceramic composed of scandium, tantalum, and oxygen, belonging to the family of perovskite-related compounds with potential applications in high-performance electronic and photonic devices. This material is primarily studied in research contexts for its potential as a dielectric, ferroelectric, or optical material, offering advantages in systems requiring high permittivity, thermal stability, or specific refractive properties compared to more conventional oxides. Its use remains largely experimental, with development focused on microelectronics, integrated photonics, and specialized sensor applications where the unique properties of rare-earth–transition-metal oxides provide performance advantages.

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.
