Technical properties for ZERODUR® glass-ceramic | SCHOTT
WEBZERODUR®. For several decades, the unique technical properties of ZERODUR® glass-ceramic have made it ideal for a vast range of applications that rely on exceptionally low thermal expansion materials. It's also now the industry standard for ultra-precise mirror substrates in astronomy.
WEBZERODUR® is widely used as a mirror substrate material and for precision frames in current state-of-the-art microlithography equipment. Specific structuring of the material allows superior stability of designs in ambitious dynamic environments, such as stages in wafer steppers and scanners.
WEBZERODUR® is a glass ceramic with an extremely low thermal expansion for demanding applications in which geometrical shape and distance changes must kept smallest possible under temperature variations. The key properties of ZERODUR® are: • Extremely low coefficient of thermal expansion (CTE) for a wide tempera-ture range
WEBZerodur is a glass-ceramic material with an extremely low CTE ( α ~ 0.05 x 10 -6 ), but otherwise exhibits most of the properties of a mormal glass, with the exception of its transmittance.
