GLASS CERAMIC – LOW CTE

Zero expansion glass ceramic with extraordinary properties for demanding applications in which geometrical shape and distance changes must be kept as small as possible during changes in temperature. Inorganic, non-porous lithium aluminum silicon oxide glass ceramic characterized by evenly distributed nano-crystals within a residual glass phase. Produced using a two-step process. During the first step, it is molten from selected raw materials, refined, homogenized and cast into moulds similar to the optical glass melting process.Following subsequent annealing for stress relaxation, a precise ceramization process transforms the material in the second step into the glass ceramic through controlled volume crystallization.
