To manufacture hermetic and highly insulating electrical seals between different materials such as metal or ceramics, the use of sealing glasses is wide spread in the electronics industry. Sealing glasses typically have a processing temperature of 800–1000°C. Sealing glasses mostly belong to the borosilicate and aluminosilicate glass families. To manufacture reliable hermetic seals, the correct choice of coefficient of thermal expansion (CTE) is a key factor. The applied glass composition depends on the materials which should be joined, the required temperature profile as well as their CTE. For matched seals, the CTE of the glass is matched as closely as possible to those of the sealing partners. In case of compression seals, a well-defined mismatch of the CTE is used intentionally to compress the sealing materials onto each other. Solder glasses, also referred to as frit glasses, are special glasses with a particularly low softening point (below 550°C). They are used to join glass to other glasses, ceramics, or metals without thermally damaging the materials to be joined. To ensure stress-free sealing, the coefficient of thermal expansion (CTE) needs to be closely matched to the sealing partners.
