  • Solder glass with refractory filler
    Patent number: 3954486
    Abstract: Disclosed is a physical blend of particulate lead borate sealing glass and particulate refractory filler for use in forming thermal fusion seals for workpieces having a lower coefficient of thermal expansion than the sealing glass. The particulate refractory filler has a particle size diameter in excess of about 37 microns (i.e. plus 400 U.S. Sieve) to lower the expansion while maintaining adequate flow during fusion. The blend is especially useful as a package sealant for electronic components.
