Silicon Nitride Ceramic

Our silicon nitride/Si3n4 proudcts offer high mechanical strength at high temperature, excellent heat shock resistance and corrosion resistance.

Main Features:

1.Corrosion resistance

Outstanding corrosion resistance to molten aluminum alloys and flux contamination free.

2.Oxidation resistance

Oxidation rarely accurs at operating temperature(up to 800 C), which allows hi-cera to maintain stable performance for a long service life.

3.Thermal shock resistance

Superior thermal shock resistance allows hi-cera protection tubes to be inserted in molten aluminum directly with simple preheating.

4.Mechanical strength

The highest strength among ceramics allows a thin wall thickness.

5.Wear resistance

Excellent wear resistance gives degassing rotor shafts a long service life at a high speed revolution.

6.Acid ressitance

Exceptional acid resistance against acids such as hydrochloric acid and sulfuric acid permits removal of sticking matter on the surface with such acids.
