Granulates & Preforms

Most sealing and solder glass powders can be further processed into ready-to-press granulates and sintered preforms of various customized shapes. Such preforms are, for example, used in glass-to-metal seals and other electronic applications.

Ready-to-press granulates are agglomerates of glass powder particles held in shape by an organic binder. While glass powders do not easily “flow” due to their irregular shape, granulates do. They are the basis for the production of sintered preforms.

Preforms are pressed and sintered glass “pearls,” rods or spacers in various shapes which are typically used in assemblies such as hermetic glass-to-metal components.

SCHOTT offers ready-to-press granulates as well as customized preforms for further processing by the customer.
