Glass solder products

Glass solders are a special class of materials designed to withstand extreme conditions. They are resistant to high temperatures, gas-tight, and chemically inert. For this reason, they are used for sealing in fuel cell stacks. There, they must withstand oxidizing and reducing atmospheres, provide electrical insulation, and endure thermal cycling.

During a joining process, the glass brazant partially crystallizes and forms a dimensionally stable glass-ceramic. Our glass brazing alloy is suitable for CFY (chromium–iron–yttrium) and ferritic interconnectors and can be used for joining steel/steel, steel/zirconia, or zirconia/zirconia.

We offer glass solder in the form of film or dispensing paste. Glass solder films are available in various thicknesses and can be cut to customer-specific geometries. In addition to our own glass solder, we can also process powders provided by customers into films and pastes.
