Glass-to-metal seals are a very important element of the construction of vacuum tubes, electric discharge tubes, incandescent light bulbs, glass encapsulated semiconductor diodes, reed switches, pressure tight glass windows in metal cases, and metal or ceramic packages of electronic components. Glass-to-Metal Seals Technical Notes. Cautions when Using GM Seals. Where glass is the transition between two fixed metal points in a vacuum system Glass-to-metal (GM) seals are joints between metal and glass tubes. They are often used to observe a process or to provide electrical isolation. Glass-to-metal seals are engineered to perform reliably in harsh operating conditions, such as extreme temperatures, moisture, pressure or chemicals. They can also fulfill requirements for longevity, performance, and efficiency improvements, as well as innovative designs. The glass-to-metal seal connects the brittle glass material to a metal with typically rather different thermal expansion coefficients. Glass to metal joints are made with metals or alloys having a value of coefficient of linear thermal expansion very close to that of the glass used in the temperature range... Glass-to-metal (G/M) sealing can be described as an art‑form based in science; meaning much of what is in practice is based on libraries of empirical data, but modern designs are now relying on analytical science. Ultimately glass to metal sealing is used to create a hermetic seal between two environments while allowing an electrical conductance path. The subsequent seal can withstand higher environmental and operational temperature than many other sealing technologies. Glass-to-metal sealing is used is to create robust electrical feedthroughs into a vacuum-tight package. This can be accomplished with two different mechanisms In a matched glass-to-metal seal, the coefficient of thermal expansion of glass, housing and pins are matched as closely as possible. Glass to metal (GTM) sealing uses a vitreous glass, devitrifying glass or glass composite to form a hermetic seal. GTM seals can be formed using paste, preforms or dry frit powder. Optical windows often use a sealing glass for hermeticity and dielectric properties. Glass-to-metal seals are a very important element of the construction of vacuum tubes, electric discharge tubes, incandescent light bulbs, glass encapsulated semiconductor diodes, reed switches, pressure tight glass windows in metal cases, and metal or ceramic packages of electronic... This paradigm has now been extended to the 110+ GHz range with the advent of the 1.0 mm coaxial connector. The fundamental electrical performance of all hermetic coaxial connector designs in the mm-wave region depends strongly on the precision of the glass-to-metal seal transition geometry.
