Silicon Nitride sialon thermocouple protection tube sheath are used extensively for continuous temperature measurement in nonferrous metals.Sialon advanced ceramics are a specialist class of high-temperature refractory materials, with high strength at ambient and high temperatures, good thermal shock resistance and exceptional resistance to wetting or corrosion by molten non-ferrous metals, compared to other refractory materials such as, for example, alumina. A typical use is with handling of molten aluminium. They also are exceptionally corrosion resistant and hence are also used in the chemical industry. Sialon also have high wear resistance, low thermal expansion and good oxidation resistance up to above ~1000 °C.


STA silicon nitride sialon thermocouple protection tube sheaths are for use in the molten aluminium and non-ferrous industry.


Sialon thermocouple protection tube sheath are very differently from slib casted syalon thermocouple protection tubes sheaths are an advanced ceramic tube offering outstanding performance for temperature control in aluminium foundries and smelters and are xtremely cost effective compared to other materials, such as cast iron, silicon carbide and alumina.


Sialon hermocouple protection tube sheaths are alloys of silicon nitride and possess a unique combination of physical properties, such as high strength, toughness, excellent thermal shock resistance and resistance to corrosion, which make it the perfect material in this application.


We have two standard diameters sialon thermocouple tubes sheaths in stock in lengths varying from 150 mm up to 1,500 mm. Tooling cost may apply. Stock items have a standard groove.


Gas-tight stainless steel adapters are specially suitable for the thermocouple protection tubes sheaths. Test our new valve adapter for low-pressure die casting machines.

Applications of silicon nitride sialon:

SiAlON advance ceramics have found extensive use in non-ferrous molten metal handling, particularly aluminium and its alloys, including metal feed tubes for aluminum die casting, burner and immersion heater tubes, injector and degassing for nonferrous metals, thermocouple protection tubes, crucibles and ladles.
