Thermocouple Alumina Thermocouple ceramic Insulator
Description:
Applications of Thermocouple Insulator:
Alumina is the best-known advanced ceramic material, is widely used in automotive, petro-chemical, fluid control,material transfer, Industry,electrical and electronic, semiconductor.Sapphire is single-crystal alumina.
Alumina ceramic is the most mature of the engineering ceramics, offering excellent electrical insulation properties together with high hardness and good wear resistance but relatively low strength and fracture toughness.
Advantage of Thermocouple Insulator:
1. Excellent electrical insulation
2. High hardness
3. Relatively low strength and fracture toughness
4. Resistance to wear and corrosive
5. Excellent thermal stability
6. Resistance to high temperatures
7. High electrical resistivity
8. Good chemical stability and resistance
9. High corrosion resistance
10.Excellent thermal shock resistance
11.High thermal insulation
