Detailed Product Description

 

Silicon Nitride (Si3N4) Pouring Spoon & Crucible

 

High-performance silicon nitride ceramic materials developed for the aluminum industry has significantly improved thermal and mechanical properties than similar products. On this basis, the "L-shaped high thermal conductivity submerged heating "Appliance" will bring revolutionary progress to aluminum industrial equipment.

 

 

The domestically pioneered grouting-formed silicon nitride pouring spoon and crucible maximizes the thermal shock resistance and non-stick aluminum properties of silicon nitride materials, and should be the ultimate solution for aluminum industry pouring spoons and crucibles.

 

 

Advantage:

 

  • Compared with the other material crucible, the service life is greatly extended.
