Silicon nitride heater protection tube is formed by CIP , then machined to accurate dimension, and put it into Reaction-Sintered furnace for sintering. The special ceramic products by this modern advanced craft 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.
