Schott Dark ROBAX® Glass Ceramic (Unverified Data**)
Categories:	Ceramic; Glass; Glass Ceramic; Optical
Material Notes:	Dark ROBAX® is an infra-red transparent glass-ceramic having virtually zero thermal expansion and sufficient mechanical resistance required for all standard applications. It is produced in rolled sheets with one surface flat and one surface textured with nubs. As a result of its extremely low thermal expansion, Dark ROBAX® can be subjected to extreme temperature differences. Even when used in high temperature conditions, Dark ROBAX® maintains excellent stability of form. Dark ROBAX® can be further processed mechanically using all of the normal methods of glass processing. Applications: Dark ROBAX® possesses a high degree of resistance against thermal stresses and chemical surface attacks. Its diverse range of applications include: high temperature vision windows for UV and visual light blocking, heat insulators, commercial heating equipment, and electronics.
