· JVASP-86450· Yb2Si2O7

Yb₂Si₂O₇ is a rare-earth silicate ceramic compound belonging to the pyrosilicate family, combining ytterbium oxide with silicate phases to create a refractory material with potential thermal and structural applications. This material is primarily investigated for high-temperature engineering environments where thermal stability and chemical resistance are critical, particularly in aerospace and energy sectors where it may serve as a thermal barrier coating precursor or monolithic refractory component. Research into rare-earth silicates like ytterbium pyrosilicate focuses on improving resistance to environmental degradation at extreme temperatures compared to conventional alumina-based systems.
