· TaAlO3

TaAlO3 is a mixed-metal oxide ceramic compound combining tantalum and aluminum oxides, belonging to the family of complex metal oxides with potential for high-temperature and electronic applications. This material is primarily of research interest rather than established commercial production, studied for potential use in capacitors, optical coatings, and high-temperature structural applications due to tantalum's excellent chemical stability and refractory properties combined with aluminum oxide's mechanical strength. The compound represents an exploratory composition in materials science aimed at tailoring dielectric, thermal, or wear-resistant properties beyond what conventional Ta2O5 or Al2O3 alone can provide.

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.
