· Sc2TiO5

Sc2TiO5 is a scandium-titanium oxide ceramic compound belonging to the family of mixed-metal oxides with potential for high-temperature applications. This material is primarily investigated in research contexts for thermal barrier coatings and refractory applications where its chemical stability and thermal properties may offer advantages over conventional oxide ceramics. The scandium dopant can modify the thermal expansion and mechanical behavior compared to pure titanium oxides, making it relevant for aerospace and industrial high-temperature environments where thermal cycling resistance is critical.
