Schott Zerodur glass-ceramic

General Introduction:

Zerodur is an inorganic nonporous lithium aluminum silicon oxide glass-ceramics, which has the characteristics of very low thermal expansion and overall uniformity. In addition, compared with other glass-ceramics, it has an extremely low defect rate, high strength, and is transparent to visible light. We can provide smooth surfaces with roughness less than the nanometer range.

Features:

1. Near zero thermal expansion

2. High uniformity

3. Available under extreme conditions

4. CNC custom 3D shapes

5. Excellent reliability

6. Low air permeability

Main Application:

1. Table and mirror for IC and LCD lithography equipment

2. A mirror base for segmented and large monolithic telescopes

3. Ultralight mirror blank

4. Technical standard for precision measurement

5. High precision mechanical parts, such as ring laser gyro body
