ABSTRACT:
The present direct invention is directed to a sealing glass composite comprising a low melting point sealing glass matrix mixed with a particulate additive to increase the effective coefficient of thermal expansion of the resulting sealing glass composite. The sealing glass matrix is in the lead borate family and the particulate additive is preferably calcium fluoride. The glass composite is particularly useful as a semiconductor package sealant.
