Long service life

Silicon nitride thermocouple 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 protective cannula 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.

Aluminum Titanate Sprue cup Description:

1,Excellent thermal shock resistance

2,No infiltration with the non-ferrous metal

3,Excellent wear resistance

4,Low thermal-expansion coefficient

Chemical content:

Si02:48.5% AL203:50.4% Ti02 0.7% Fe2030.14% NaO2≤1.0% Dregginess ≤0.05% other ≤0.05%

The aluminum titanate has higher melting point(1860°C±10°C),lower thermal expansion coefficient(RT—1000°C,α<2.0×10-6/°C) and excellent heat-shock resistance .Besides,the aluminum titanate don’t infiltrate with the metal melt(especially the non-ferrous metals) and glass melt.Therefore aluminum titanate can be widely used in the conditions of high-temperature resistance,heat-shock resistance and corrision resistance.


Aluminum Titanate sprue bush made by Zibo Taisheng Industry& Trade is used to dose the molten aluminum from the container to the mould.


We can produce different sizes according to the customers’ requirement.
