YB5996 Ytterbium Silicate Powder Yb2Si2O7

Yb2Si2O7-Powder Description:

Yb2Si2O7-Powder is an agglomerated and sintered ytterbium disilicate material, specifically designed for use in atmospheric plasma spraying processes. This powder serves to produce high-density environmental barrier coatings (EBCs), providing substantial protection for ceramic matrix composites (CMCs) that face extreme temperatures. With a maximum operating temperature of up to 1350°C (2460°F), Yb2Si2O7 coatings are highly effective in shielding lightweight, silicon-based CMCs from thermal damage. Key properties of Yb2Si2O7 include a low thermal expansion coefficient, low thermal conductivity, and excellent phase stability, essential for maintaining coating integrity over time and temperature. Typically, these coatings are applied over silicon or silicon-based cermet bond coats and are utilized in high-performance applications such as blade profiles, combustion chamber linings, blade paths, covers, and exhaust components.
