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.
