Nitride Bonded Silicon Carbide Thermocouple Protection Tube
1. Contents: RSiC, NSiC
2. Function: Our alumina ceramic tube can protect the thermocouple wire from oxidation and corrosion. Its thermal conduction is quite good.
Feature of Nitride Bonded Silicon Carbide Thermocouple Protection Tube
NSiC is made of high-purity silicon carbide powder and Si powder, formed by slip casting, and reacted and sintered in vacuum furnace. This kiln furniture has great high-temperature strength and low weight.
