Microcertec - Ceramic Components for Power Electronics
There are numerous benefits to use ceramics in the field of power electronics. Advanced ceramics resist to severe environments, demonstrate excellent properties of electrical insulation, low thermal expansion, dimension stability at extreme temperatures and high corrosion resistance.
Also, they are clean materials in view of their high purity levels, and with no open porosities they do not outgas in high-vacuum.
In addition to bare ceramic products, Microcertec can also offer metallized ceramics and ceramic-to-metal brazed assemblies that are hermetic in vacuum and ultra-high vacuum - UHV.
Advanced ceramic components and brazed ceramic-to-metal assemblies are primarily used in the following power electronics equipment :
- electronic tubes
- power modules
- vacuum interruptors
The most commonly used advanced ceramic materials for power electronics are :
- alumina – 94 to 99.8 % (aluminium oxide)
- aluminium nitride (AlN)
- macor ®
- quartz
