Joining Behavior of Ceramics to Metal by Using Lead-bismate Heavy Metal Glass Frit

ABSTRACT
The joining behavior of forsterite ceramics to SUS304 alloy using $8PbO-78Bi_2O_3-8B_2O_3-4ZnO-2SiO_2$ (wt%) system glass frit was investigated. The contact angle was smaller than $90^{circ}$ at a temperature of $460^{circ}C$. Redox reaction at the interface between forsterite and SUS304 was found to appear when the electrons in the metal part moved toward the glass part and the oxygen ions in glass moved to the metal side. The decrease of the surface tension due to the PbO solubility on the forsterite side contributed to the better wetting behavior at low temperature.
Key words: Forsterite, SUS304, Glass frit, Redox reaction, Solubility, Joining
