Sealing glass composition |
摘要 |
Lead borate and lead zinc borate glasses containing from 0.1 to 10% by weight cuprous oxide (Cu2O) and fluoride, the molar ratio of cuprous oxide to fluoride being in the range 1:0.25 to 1:10, preferably in the range 1:1 to 1:5, and up to 5% by weight bismuth oxide. These glasses may be mixed with particulate refractory fillers in amounts up to about 56% by volume. The sealing glasses are useful for bonding ceramic, glass and metal parts together at low temperatures. They are especially useful as semiconductor package sealants.
