So called Solder Glass serves the purpose to produce glass-to-glass sealings and glass-to-metal or ceramic sealings.
Solder Glass is used where direct sealing is not possible for technical reasons.
It is applied in form of a powder with a grain size minor than 65 µm which is converted into a paste or suspension using an evaporating liquid. The usage of the pure powder is possible as well.
It can be applied in form of a lane, with serigraphy, by spraying or as powder particles.
Solder Glass with its very low softening temperature of only 380 °C avoids a deformation during the thermal processing and assures a firm and, if necessary, vacuum-tight connection.
TELUX produces glass solder with various thermal coefficients of expansion. It is used for solar cells, thermal panes and cathode ray tubes.
