NSiC Thermocouple Protection Tube
Product Information
Silicon Nitride Si3N4 Bonded SiC Silicon Carbide Thermocouple Protection Tube
Si3N4 bonded SiC ceramic refractory material, is mixed with high pure SIC fine powder and Silicon powder, after slip casting course, reaction sintered under 1400~1500°C. During the sintering course, filling the high pure Nitrogen into the furnace, then the silicon will react with Nitrogen and generate Si3N4, So Si3N4 bonded SiC material is composed of silicon nitride (23%) and silicon carbide(75%) as main raw material, mixed with organic material, and shaped by mixture, extrusion or pouring,then made after drying and nitrogenization.
Features:
High temperature stability: It can maintain structural stability at temperatures up to 1500 degrees Celsius to ensure the normal operation of the thermocouple.
Chemical stability: It can resist the erosion of strong acids, strong alkalis and other chemicals, and protect the thermocouple from chemical corrosion.
High strength and high hardness: It has good impact resistance and wear resistance, and can be used for a long time in harsh working environments.
Good insulation performance: It can effectively prevent the thermocouple from electromagnetic interference during operation and ensure measurement accuracy.

Application
Petrochemical industry: Provide reliable temperature measurement protection in high temperature and highly corrosive environments.
Steel smelting: Ensure temperature measurement accuracy and stability during smelting.
Ceramic production: Protect thermocouples during high temperature firing.
Glass manufacturing: Measure temperature during high temperature melting.
Non-ferrous metal casting: Especially in the smelting of metals such as aluminum, zinc, copper, and magnesium, it can provide long-term stable service life and efficient temperature response.
This protective tube is particularly prominent in the non-ferrous metal casting industry. For example, in the aluminum products industry, it can isolate the contact between aluminum liquid and silicon carbon rods, protect silicon carbon rods from damage, and can also be used for aluminum liquid transmission during aluminum wheel manufacturing.
