Recrystallized Silicon Carbide Protection Tubes



RSiC Thermocouple Protection Tubes With One End Closed


Recrystallized silicon carbide tubes are produced by pure silicon carbide powers, and sintered by vacuum furnace under temperature 2500℃ . During the production, no binders are added,so Recrystallised Silicon carbide have very good performance under higher temperature, the max use temperature can be up to 1650℃.


Advantages:

@Extremely high hardness

@High thermal conductivity

@Higher Young’s modulus

@1650℃ Higher temperature resistance

@Outstanding thermal shock resistance

@ good wear resistant and corrosion resistant
