Ceramic Reaction Bonding Silicon Nitride Si3N4 Tube And Pipe For High Refractoriness

Refractory Silicon nitride thermocouple protective tube ( protection tube) is formed by CIP biscuit, 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 protection tube measuring temperature of molten aluminum for its anti-fusion.

Silicon nitride ceramics possess excellent properties of high thermal stability, antioxidant capacity and good dimensional precision of products. As silicon nitride is covalent compounds with high bond energy and can form protective film of oxide in the air, so its good chemical stability can make silicon nirtide not be oxidized below 1200°C, and generate protective film to prevent further oxidation between 1200~1600°C. Silicon nitride can not be infiltrated and corroded by aluminium, lead, tin, silver, brass, nickel and other molten metals, but can be corroded by molten metal like magnesium, nicochrome and stainless steel.
