Glass Type: Glass Ceramics
Description
SCHOTT ROBAX® is a highly transparent glass ceramic having virtually zero thermal expansion and sufficient mechanical resistance required for all standard applications. It is produced in flat, rolled sheets. As a result of its extremely low thermal expansion, SCHOTT ROBAX® can be subjected to extreme temperature differences
