The company manufactures ZERODUR, an inorganic, non-porous glass ceramic, characterized by a phase of evenly distributed nano-crystals within a residual glass phase. ZERODUR contains about 70-78 weight percent crystalline phase with a high quartz structure. This crystalline phase has a negative linear thermal expansion, while that of the glass phase is positive. The crystals have an average size of about 50 nm.
