Zerodur Glass-Ceramic

Zerodur is a glass-ceramic material characterized by an almost negligible coefficient of thermal expansion. It is produced by Schott AG in Germany and is particularly well-suited for applications that demand exceptional thermal stability. The volumetric stability of Zerodur in response to temperature fluctuations makes it ideal for use in highly precise optical instruments and scientific apparatus.

The Distinctive Performance Characteristics of Zerodur

Zerodur exhibits a low coefficient of thermal expansion, resulting in minimal dimensional changes in response to temperature fluctuations. This characteristic renders it particularly well-suited for high-precision applications.

The thermal stability of the material allows it to retain its shape and dimensions even under extreme environmental conditions, making it widely applicable in fields such as aerospace and astronomy.

Zerodur exhibits exceptional resistance to chemical corrosion, thereby ensuring its long-term stability in adverse conditions.

The primary application domains of Zerodur.

The material Zerodur is frequently employed as the substrate for mirrors in astronomical telescopes, as it provides optical stability in environments characterized by significant temperature variations.

In the realm of semiconductor manufacturing equipment, Zerodur is employed to produce mechanical components that adhere to stringent specifications, thereby minimizing errors attributable to thermal expansion.

In the field of optics and laser technology, the low thermal expansion properties of Zerodur glass ceramic materials are essential for optical components that necessitate exceptionally high precision, such as mirrors and laser beam guidance systems.
