Product Details
Wear Resistant Silicon Nitride Ceramic Thermocouple Protection Tube
for Sale
Advantages
Silicon nitride ceramic thermocouple protection tube protects the
sensitive thermocouple element from aggressive compounds in the
furnace atmosphere. Due to their very good thermal conductivity,
the accuracy of the thermocouple reading is increased.The silicon
nitride ceramic has very high working temperature, up to 1200℃.It
has good chemical resistance and good thermal conductivity for
accurate metering.
Features
1. Long service life
2. Sintering: GPSN/RSSN (gas pressure sintering, reaction
sintering)
3. Good abrasive resistance
4. Excellent thermal shock resistance
5. Top refractory
6. Reduced maintenance requirements and ease of maintenance
7. Anti-corrosion in the high-temperature
8. Perfect electrical insulation resistance
9. Customization available
Product Description
Silicon nitride ceramics characteristics and its low weight make
silicon nitride an excellent material choice for demanding
applications. This is why components made of silicon nitride
ceramics are successfully used in various welding processes.
We can supply advanced technical ceramic part according to
