Glass joint body and method of manufacturing the same.

摘要

In order to improve a reliability of a glass joint body, first ceramic member (1) and second ceramic member (6) are connected by using (a) glass consisting of 10-65% weight SiO2, 30 wt% or less of Na2O, and the balance of B2O3 and Al2O3, (b) glass including less than 10 wt% of SiO2, and 30-80 wt% of B2O3, (c) glass including substantially none of SiO2, and 30-80 wt% of B2O3, or (d) glass consisting of 10-65 wt% of SiO2, 20 wt% or less of Na2O, 30 wt% or less of Al2O3, 20 wt% or less of MgO, and the balance of B2O3. The glass has good resistance to sodium corrosion.
