· TiAlO3

TiAlO3 is a titanium aluminate ceramic compound combining titanium and aluminum oxides into a single-phase crystalline structure. This material is primarily of research and specialized industrial interest, particularly in high-temperature applications where thermal stability and chemical inertness are critical. It is valued in sectors requiring refractory components, advanced catalytic supports, and thermal barrier coatings where conventional oxides may fall short in performance or cost-effectiveness.

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.
