Silicon Nitride Ceramic Protection Tubes


Silicon Nitride Ceramic

Product Category:

Ceramic Protection Tube

INNOVACERA manufactures a range of silicon nitride and advanced ceramic thermocouple protection sheaths for use in the aluminum and molten metal handling industries. They are an advanced ceramic tube offering outstanding performance for temperature control in aluminum foundries and smelters and are extremely cost-effective compared to competitive materials, such as cast iron, silicon carbide, and alumina. Its outstanding performance is in contact with non-ferrous molten metals, particularly aluminum and its alloys and zinc. They allow constant temperature monitoring of the melt resulting in improved quality of the finished casting.

The unique combination of physical properties:
Maximum temperature of 1400 “C in air
High strength, toughness
Excellent thermal shock resistance
Resistance to corrosion

For both, direct as well as indirect temperature sensing in molten metal (e.g. furnace wall or roof )
For temperature reading for low-pressure-die-casting machines (e.g. Aluminum wheel manufacturers)
For temperature measurements in non-ferrous launders or pouring troughs
