· Sc2 Ti2 O7

Sc₂Ti₂O₇ is a ceramic pyrochlore compound composed of scandium, titanium, and oxygen, belonging to the family of mixed-metal oxides with potential semiconductor properties. This material is primarily investigated in research contexts for thermal barrier coatings, solid-state electrolytes, and advanced refractory applications, where its high thermal stability and ionic conductivity make it attractive for extreme-temperature environments. As a relatively specialized research compound, it offers potential advantages over conventional thermal protection systems in aerospace and high-temperature industrial settings, though widespread industrial adoption remains limited compared to established alternatives like yttria-stabilized zirconia.

Export Control

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.
