Silicon nitride thermocouple protection tube for formed by CIP , then machined to accurate dimension , and put it into Reaction-sinted furnace for sintering.

 Silicon nitride thermocouple protection tube have the characteristics of high and equal density , good dimensity accuracy , etc . Silicon nitride is especially suitable for thermocouple protective cannual measuring temperature of molten aluminum for its anti-fusion. Our company can do any types as customers' required.

Feature:

1. High strength & good compactness

2. Low thermal expansion coefficient

3. Excellent thermal shock coefficient

4. No wetting by molten aluminium and other non-ferrous molten metal

5. Good corrosion resistance

Application:

Used to protect the temperature-measuring components , make the components isolate from the outside substance , reduce and prevent the corrosion , oxidation and mechanical damage to the components during measuring.
