06 – FAQ
Frequently Asked Questions
Why is outgassing important in vacuum applications?
Materials used in vacuum systems can release small amounts of trapped or adsorbed gases over time. Excessive outgassing can affect vacuum quality, contaminate sensitive surfaces and compromise equipment performance.
SCT combines carefully selected materials with controlled manufacturing, cleaning, inspection and handling processes for demanding high-vacuum applications.
What is bake-out compatibility?
Vacuum systems may undergo controlled heating to remove moisture and volatile contaminants before operation.
Ceramic-to-metal assemblies used in these environments must withstand repeated thermal cycles while maintaining their mechanical, electrical and vacuum performance.
Why are ceramics used in high-voltage vacuum equipment?
echnical ceramics combine high electrical insulation with thermal stability, mechanical strength and compatibility with demanding vacuum environments.
When combined with metallization and ceramic-to-metal brazing, they enable robust electrical insulation and vacuum-compatible interfaces between metallic components.
