SILICON NITRIDE SYALON COMPONENTS

1.Khả năng chống sốc nhiệt

Si3N4 or Sialon/Syalon has superior thermal shock resistance and high temperature mechanical strength.

Prior to the application of Si3N4 or Sialon/Syalon products, preheating is necessary. The preheating process can realize better reliability than conventional ceramic.

2.Resistance to corrosion

Si3N4 or Sialon/Syalon has excellent corrosion resistance,being almost inert against molt aluminum, thus ensuring longer life.

3.Low- wettability

As a covalent binding ceramic，Si3N4 or Sialon/Syalon has low wettability against molten metal and does not require coating. lt will not generate much scorification and material adsorption, as a result, it is easy to clean.

4.Low heat conduction

Si3N4 or Sialon/Syalon has the advantage of low heat conduction. lts low specific heat reduces loss of heat to the minimum. This guarantees the accuracy in temperature measurement for the thermocouple protection tubes,and facilitates molten metal heat to convey in stalk tube.This can reduce the temperature of molten aluminum and save overall energy costs.

5.Cường độ cao,long life

Si3N4 or Sialon/Syalon keeps its original strength even at high temperature of up to 800°C. lts corrosion resistance and excellent strength characteristics permit a relative thin wall in thickness of the products，making it easy to handle and operate, and for maintenance and replacement.
