It can be sealed with molybdenum glass, and is usually hard glass such as DM305 or DM 308. The above two molybdenum glasses and the thermal expansion coefficient were also in the range of 48 x 10-7 to 50 x 10-7.
The disadvantages of this are: the process is complex, the requirement on the expansion coefficient of the material is high, high equipment investment of a high-temperature atmosphere melting sealing furnace is required, and the shell machining and the material cost are high; the cost of single coating is high and is not matched with the expansion coefficient of the copper base.
