Hermeticity – Maximum leak rate is 1 x 10-9cc helium/second
Terminal Strength – Can withstand forces up to 9000 psi without affecting hermeticity
Mechanical Shock and Vibration – Repeated shocks in excess of 1000g’s and swept frequency vibration from 5000 to 2000 cycles at 60g’s have produced no evidence of seal deteriation
Chemical Stability – Ceramic seals operate from +600°C to -270°C and cannot absorb water. They are more chemically inert than glass and are not affected by acids, strong alkali’s and organic solvents.
Insulation Resistance – Ceramic insulators are nonporous, nonhydroscopic and exhibit superior insulation resistance and less loss under high voltage than glass
Closure Methods – Various final sealing designs are available for resistance welding and high energy beam welding
