Silicon Nitride Protection Sheath 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.
