HighAlumina/Ceramic Insulation Tubes/High Temperature Insulation,ceramic insulation tubes
Ceramic insulators are used when electrical insulation isnecessary in high heat applications. This makes them useful forsupporting electric heating elements in ovens, heaters andfurnaces.
Ceramicshold their shape and size under pressure. This is important inswitching applications where the ceramic is used to open and closeelectrical contacts in a thermostat or pressureswitch. Ceramicparts are very abrasion resistant and offer long life inapplications where other materials would wear outquickly.
1. Advanced ceramics -Change the world!
- low density
- high hardness
- high mechanical strength
- dimensional stability (specific stiffness)
- resistance to wear
- resistance to corrosion (resistance to chemical attack)
- weathering resistance
- high working temperature
- low or high thermal conductivity
- good electrical insulation
- dielectric and ferroelectric properties
