Abstract: Low-melting, low-expansion, lead-free glass compositions are provided for sealing ceramics parts and encapsulating ceramic substrates. In addition to having a thermal expansion matching that of alumina, the glass compositions provide for the formation of a glass-to-alumina seal in the 380* to 450* C. temperature range.
