Silicon Nitride Thermocouple Protective Tube
Silicon nitride thermocouple protection tube is formed by CIP , then machined to accurate dimension, and put it into Reaction-Sintered furnace for sintering.
Silicon nitride thermocouple protection tube have the characteristics of high and equal density, good dimensional accuracy , etc. Silicon nitride is especially suitable for thermocouple protective cannula measuring temperature of molten aluminum for its anti-fusion.Our company can do any types as customers’ required.
