Abstract
Sealing glass compositions are described which have low sealing temperature requirements and are particularly useful for sealing together the ceramic components used in microelectronic circuitry. The sealing glass compositions are characterized as low temperature, low expansion glasses of high chemical resistance especially against acid attack. Formed of a mixture of a lead borate base glass and beta eucryptite, the sealing glasses of the invention also possess high mechanical and thermal shock strength.
