    Si3N4 bonded SiC thermocouple protection tube/The nitrogen bonded silicon carbide/silicide thermal protection tube/top refractory protection tubes/high strength thermal tubesis made by firing mixtures of high purity silicon carbide and silicon or a mineral additive in a nitrogen atmosphere at high temperature (typically ***0ºC to ***0ºC). The silicon carbide is bonded by the silicon nitride phase (Si3N4) developed during nitriding. The maximum operating temperature of the resulting material is around ***0ºC.
