Yb2Si2O7 Powder Description:
Yb2Si2O7 Powder is an agglomerated and sintered material composed of ytterbium disilicate, specifically developed for use in the atmospheric plasma spray process. This powder is designed to create high-density Environmental Barrier Coatings (EBCs) that provide strong protection for Ceramic Matrix Composites (CMCs) exposed to extreme temperatures. With a maximum operating temperature of up to 1350°C (2460°F), Yb2Si2O7 coatings are highly effective in protecting lightweight, silicon-based CMCs from thermal damage. Key properties of Yb2Si2O7 include a low thermal expansion coefficient, low thermal conductivity, and excellent phase stability, which are essential for maintaining coating integrity over time and temperature. These coatings are typically applied over silicon or silicon-based cermet bond coats and are used in high-performance applications such as airfoils, combustor liners, blade tracks, shrouds, and exhaust components.
