Abstract
This invention relates to sealing mixtures consisting essentially of a sealing glass having a low sealing temperature and a high coefficient of thermal expansion, and a glass-ceramic additive that imparts a lower effective coefficient of expansion to the sealing mixture with a minimum effect on glass flow at the sealing temperature. It further concerns the use of this mixture to produce fusion seals between elements, particularly elements in electrical and electronic components.
