Glass Metal Seals

NIMRA has developed glass ceramic seals for high performance application that are beyond the capabilities of traditional glass to metal seals. This glass partially crystallizes during the sealing process to form a reinforced glass / ceramic, which can withstand temperatures up to 900 °C.

Some application examples of glass to metal seals and ceramic glass seals are as follows:

1. Semi conductor engineering - (transistors, diodes, power rectifiers and thyristors)
2. Vacuum-tight capacitors for use in the tropics and at high altitude
3. Hermetically encapsulated relays and circuit elements
4. Pressurized transformers, motors and switches.
5. Construction of power tubes
6. Air-tight encapsulated compressors for refrigerators
7. Measuring instruments
8. Vacuum engineering
9. Vacuum-tight and pressure-resistant window sealing
10. Glass-metal sealed penetrations for control, measuring and power lines in reactor construction.
